If the load used is lamp then, the brightness of the lamp increases as the number of lamps is decreased. Electricity can be present in a static charge, while magnetism’s presence is only felt when there are moving charges as a result of electricity. In the CBSE Class 10 Physics syllabus, there are crucial topics such as electricity, magnetic effects of electric current, refraction of light, etc. PHYS1112 - Electricity and Magnetism Lecture Notes Dr. Jason Chun Shing Pun Department of Physics The University of Hong Kong January 2005 The phenomenon of inducing the emf in a closed circuit whenever there is change in the magnetic flux is called electromagnetic induction. The magnitude of the induced emf is directly proportional to the rate of change of the magnetic flux. To assist you with that, we are here with notes. If the one of the resistor do not work then it effects the whole combination. It converts 10% of the electrical energy into light energy. The process of the decomposition of the electrolytic solution into constituent when the electric current is passed through it is called Electrolysis of water. This is possible only when you have the best CBSE Class 10 Science study material and a smart preparation plan. Temperature is the measure of how hot or cold a body is. 3. Cot 5π/20 .

The resulting current is called induced current. It cannot be used in transformers. Positive and negative charges: The charge acquired by a glass rod when rubbed with silk is called positive charge and the charge acquired by an ebonite rod when rubbed with wool is called negative charge. It is used in power stations to transmit current to long distances. It can be used in transformers. 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. he electricity produced due to the flow of electrons through a conductor is called current electricity. 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.

Arrangement of the cells which is designed to get the maximum potential difference and current supply is called combination of cells. Substances to which electroplating is to be done should be connected as anode, and to which it should be done is connected as cathode. It is filled with Mercury vapour. The current flowing in the circuit doesn't increase with the increase in number of cells. An electromagnet is a type of magnet which possess magnetism by application of electricity. If sinA = 12/13 , find cosA and tanA. 2.

Fluorescent powder is used as the main lightning element in fluorescent lamp. Want to learn by Video Lectures? Connecting two or more than two electric loads might be necessary sometimes. The induced pd lasts as long as there is change in magnetic flux. It is filled with inert gases. The overflow of the current due to the low reactance path in the circuit is called short-circuiting. Electric Current: The flow of electric charge is known as Electric Current, Electric current is carried by moving electrons through a conductor. Cot7π/20 . If the load used is lamp, the brightness of lamp isn't affected by the decrease or increase in the number of lamps. Transformers are used in computer, television, air condition, doorbells etc. The transformer which converts low AC voltage to high AC voltage is called step up transformer. → Magnet is any substance that attracts iron or iron-like substances. Electric Power (P) = electric work (W) / time taken(t). 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.

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. If forefinger pointing the direction of magnetic field, the thumb pointing the direction of motion of the conductor, them the central finger points the direction of induced current.". Its average life span is about 3000 hours. If R1 R2 R3 R4 are connected as shown in figure then. The course notes were written by John Belcher, Peter Dourmashkin, and Sen-Ben Liao. In this case total current (I) = I1 + I2 + I3 …………………..1. The TEAL classroom includes the opportunity for students to use the Personal Response System (PRS). This effect of electric current is called its chemical effect. The electrical power of device is the product of the current (I) and voltage (V) across. It is called the principle of mutual inductance on which transformers are based. According to Oersted's experiment, it is known that a current produces a magnetic field. Sources are AC generators or dynamic. 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. When electric current is passed through a substance, it brings about a chemical reaction in that substance. 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. 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.

The circuit in which switch is open and the electric current does not flow in the circuit is called open circuit. Cot 7π/20 . The strength of an electromagnet depends on: b) amount of current supplied in the circuit, c) purity of soft iron core [ increasing the purity of soft iron core also increases the strength of an electromagnet.
