Cot 3π/20 . Total potential in this case (V) = sum of the individual p.d of the cell. A florescent lamp consists glass tube filled the mercury vapor and coated with florescent powder. It can be used in transformers. (ii) Comes to rest in North-South direction, when suspended freely. This is question from the Values of Trigonometric Ratios chapter of Unit Trigonometry. ]. Substances to which electroplating is to be done should be connected as anode, and to which it should be done is connected as cathode. 3. Here, we will discuss current electricity, circuit, effects of current electricity and about transformer. The resulting current is called induced current. Electroplating is the process of depositing one metal over another by electrolysis. View and Download PowerPoint Presentations on Electricity For Class 10 PPT. Fleming’s right hand rule states that “If the first three fingers of the right hand are held mutually perpendicular to each other, with the index finger in the direction of the magnetic flux and the thumb in the direction of motion of coil, the middle finger points to the direction of the induced current.”. 1. 2. This is called electrolysis of water. Cot 3π/20 .cot5π/20 .

Power of the bulbs used (P) = 100 W = 100/1000kw  = 0.1 kw, Electrical energy consumed by bulbs in a day (E)= P x N x t= 0.1 x 20 x 5= 10 kwh, Electricity consumed in one month by bulbs = 10 x 30= 300 kwh, Power of the fans used (P) = 75 W = 75/1000 kw = 0.075 kw, Electrical energy consumed by fans in a day = P x N x t= 0.075 x 6 x 5= 2.25 kwh, Electricity consumed in one month by fans = 2.25 x 30 = 67.5 kwh, Now, total energy consumed in that month = 300 + 67.5= 367.5 kwh, Amount of electric bill = energy consumed x rate = 367.5 x 7 = Rs. he electricity produced due to the flow of electrons through a conductor is called current electricity. According to Oersted's experiment, it is known that a current produces a magnetic field. → An electric current-carrying wire behaves like a magnet. Water decomposes into its constituent components when it passes through electricity. Notes For Electricity And Magnetism Class 10 Magnetism And Electricity Questions For Tests And Worksheets. Therefore, the current used by the heater is 4A and a fuse of 5A is needed to be put into the heater. Whenever magnetic flux linked with a closed circuit changes, an emf is induced in the circuit. 9841851000, 9851144617, 9841279140, 9851174547. Machines based on motor effect convert electrical energy into mechanical energy. Electric circuit: Electric circuit is the combination of source of current, conducting wires, and loads. 3. This is why the current cannot flow completely throughout the circuit. It is used in the construction of electric heater, rice cooker, toaster, etc. If the load used is lamp, the brightness of lamp isn't affected by the decrease or increase in the number of lamps.

A generator or dynamo is a machine that converts mechanical energy into electrical energy thus, is used to produce electricity. Magneto-static:- It is the study of magnetic fields in systems where the currents are steady (not changing with time).It is the magnetic analogue of electrostatics, where the charges are stationary. i.e. The induced emf lasts as long as the change in the magnetic flux is taking place. Faradays laws of electromagnetic induction are: 1. It converts 10% of the electrical energy into light energy. The total resistance can be measured as: 1/R = 1/. This is the type of electric circuit in which the electric load glows and current can completely flow throughout the circuit because the connecting wires are good and the switch is also turned on. Its average life span is about 3000 hours. It is used in power stations to transmit current to long distances. Magnetic field due to current in a solenoid. The magnitude of the induced emf is directly proportional to the rate of change of the magnetic flux. It converts 10% of the electrical energy into light energy. It is called the principle of mutual inductance on which transformers are based.

The current in the external resistance is the number of times the current due to t e single cell. And, according to Michael Faraday, magnetism produces current through electromagnetic induction. This causes to change the magnetic flux linked with the secondary coil. There are two types of electric circuits: This is the type of electric circuit in which the electric load doesn't glow because either the connecting wire is faulty or the switch is turned off. The cells are said to be parallel if the positive terminal of all cells are connected at one common point and the negative terminal are connected to one common point. Unit-6 | ELECTRICITY & MAGNETISM | Class-10 Overview: Electricity is a form of energy produced either due to the change in number of electrons in a body or due to the flow of electrons through a conductor. It is used to construct electric bulbs, lamps and fluorescent lamps. Those substances that can produce electricity are called the sources of electricity.There are two kinds of electricity: The electricity produced due to the change in number of electrons in a body is called static electricity. It converts 30% of the electrical energy to the light energy and very useful for the household purposes. • Unlike electricity, magnets do not come in separate charges. R= R1 + R2 + R3 and if V1 V2 V3 are the voltage across resistors respectively. Electromagnetic Induction is the production of electromotive force across an electrical conductor due to the change in magnetic field. In parallel combination of cells the total voltage between any two points is always constant this is equal to the voltage of one cell. - Pressure Proof Liquid pressure is the pressure exerted by the liquid per unit area of the surface.

The cells can be used by combining or joining them together in the following ways: In this combination, the cells are connected in such a way that the positive terminal of a cell is connected to the negative terminal of another cell. If sinA = 12/13 , find cosA and tanA. is the electricity whose polarity doesn't change with time. If R1 R2 R3 R4 are connected as shown in figure then. St Mary s HS Physics Magnetism Notes. of turns in primary coil (Np). Temperature is the measure of how hot or cold a body is. They are of two types: The circuit in which switch is closed and the electric current passes in the circuit is called closed circuit. The phenomenon of inducing the emf in a closed circuit whenever there is change in the magnetic flux is called electromagnetic induction. In this case total current (I) = I1 + I2 + I3 …………………..1. When the resistors in the circuit are connected between the two common points, then the combination is called parallel combination.

"The thumb, forefinger and the central finger of the right are stretched so that they are mutually perpendicular to each other. of turns in secondary coil (Ns) / No. If the one of the resistor do not work then it effects the whole combination. The state in which a conductor shows magnetism when electric current is passed through it, it is called magnetic effect. This effect is called the heating effect of electric current. Dronstudy provides free comprehensive chapterwise class 10 Science notes with proper images & diagram. The value of the current is same in each resistor but the p. d is different. c) It is used in MRI machines to take photos of the view of human's internal organs. Batteries, DC generators are the examples of it. 1. The total resistance can be measured as: R = R, In this combination, the loads are connected in such a way that all the positive terminals are joined at a point and all the negative terminals are joined at another point. When an alternating emf is applied to the primary coil, a changing current flowing in it produces an alternating magnetic flux in it. At anode:      Cu   +   SO4   →    CuSO4 + 2e, Some electricaldevices converts electrical energy into the light energy this is called lighting effect of electric current.
