Ohm's law: The electric current (i) in a conductor is proportional to the potential difference (V) between its ends of a constant temperature (T).
Verification: To verify Ohm's law, a battery; (B), ammeter (A). resistance (R), voltmeter (V), tap-key (K), rheostat (Rh) are connected as shown in circuit diagram. Voltage (v) across the resistor can be recorded by voltmeter (V) and current (i) can be recorded by ammeter (A) in the table given below and the ratio V/i can be calculated. Repeat the experiment five times by changing current in the circuit with the help of rheostat. Note the readings in the table.
From the above table it is observed that the ratio v/i is always constant. Hence ohm's law is verified. i.e., The resistance of a conductor remains constant at constant temperature no matter what applied voltage is used to measure it.
two insulated charged copper spheres A and B of identical size have charge q and -3q respectably .when they are brought in contact with each other and then separated,what are the n
As we''re on an inclined plane shouldn''t we take the x & y components of gravity into consideration?? thanks
the theory for this motion
The phase of weightlessness may be observed in the following situations: (i) When objects fall freely under gravity : For example, a lift goes down freely, or an airship showing

Q. What is superconductivity? The capability of certain metals their compounds and alloys to conduct electricity with zero resistance at very low temperatures are called superc
A simple calorimeter Small soup tins can be found which fit loosely into a 1lb. jam jar. If the top of the tin is cut off cleanly with a rotary type opener it serves as an good

Two students, A and B, living in neighbouring college rooms, decided to economise by connecting their ceiling lights in series. They agreed that each would install a 100-W bulb
Explain the Adding Waves? When two waves come from the same light source, the light waves are coherent, meaning that the phase difference between the waves is constant in time.
