Therefore, the current used by the heater is 4A and a fuse of 5A is needed to be put into the heater. It is used in the construction of electric heater, rice cooker, toaster, etc. Total potential in this case (V) = sum of the individual p.d of the cell. It is used to construct electric bulbs, lamps and fluorescent lamps. MIT. Transformer is a device which changes low AC voltage to a high AC voltage or high AC voltage to low AC voltage. Candidates who are ambitious to qualify the Class 10 with good score can check this article for Notes. Magnetic field due to current in a solenoid. The current flowing in the circuit increases with the increase in the number of cells. The current flowing in the circuit doesn't increase with the increase in number of cells. Filament lamp has tungsten filament with inert gases filled inside the bulb. The total pd is equal to the individual pd of each cell. i.e. A generator is a machine which converts mechanical energy into electrical energy. To register Science Tuitions on Vedantu.com to clear your doubts. An alternating emf is then induced in the secondary coil. Unit-3  | SIMPLE MACHINES  |  Class-09 Overview: All the tools that make our work easier are machines. • Any magnetic/magnetized object has a North and South pole. When an alternating emf is applied to the primary coil, a changing current flowing in it produces an alternating magnetic flux in it. 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. b) It is used to remove pieces of iron from wound. Arrangement of the cells which is designed to get the maximum potential difference and current supply is called combination of cells. Electric Current: The flow of electric charge is known as Electric Current, Electric current is carried by moving electrons through a conductor. The electrode connected to the positive terminal of cell is called anode. Cot 7π/20 . The overflow of the current due to the low reactance path in the circuit is called short-circuiting. Introduction to Electricity The path that is made of a conducting wire that carries current from negative terminal of a source to positive terminal of the source is called electric circuit.

Fleming's left hand rule states that, "if the first three fingers of our left hand are stretched so that they are mutually perpendicular to each other with the forefinger pointing the direction of magnetic field, middle finger pointing the direction of current, then the motion of conductor is given by the thumb. 9841851000, 9851144617, 9841279140, 9851174547. 1. 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. A generator or dynamo is a machine that converts mechanical energy into electrical energy thus, is used to produce electricity. The induced pd lasts as long as there is change in magnetic flux. If tanA = 5/6 and tanB = 1/11, prove that: A+B = 45° or prove that: A+B = pi/4 or find the value of A+B. When current carrying conductor is kept in magnetic field, it starts to move which is called motor effect. The phenomenon of inducing the emf in a closed circuit whenever there is change in the magnetic flux is called electromagnetic induction. Substances to which electroplating is to be done should be connected as anode, and to which it should be done is connected as cathode. → Electromagnets and electric motors involve the magnetic effect of electric current, and electric generators involve the electric effect of moving magnets. 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. Electromagnetic Induction is the production of electromotive force across an electrical conductor due to the change in magnetic field. basic principles in electricity and magnetism Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.
