The current passing through an electric kettle has been doubled. The heat produced will become:

If the current flowing through a fixed resistor is halved, the heat produced in it will become:

If the current flowing through a fixed resistor is halved, the heat produced in it will become:

(a) Derive the expression for the heat produced due to a current 'I' flowing for a time interval 't' through a resistor 'R' having a potential difference 'V' across its ends. With which name is this relation known? (b) How much heat will an instrument of 12W produce in one minute if its is connected to a battery of 12V? (c) The current passing through a room heater has been halved. what will happen to the heat produced by it? (d) What is meant by the heating effect of current? Give two applications of the heating effect of current. (e) Name the material which is used for making the filaments of an electric bulb.

When current passing through a coil is made doubled, its self inductance ......

The electric current passing through a metallic wire produces heat because of

A given conductor carrying a current of 1 A produces an amount of heat equal to 2000 J. If the current through the conductor is doubled, the amount of heat produced will be

Assertion If current passing through a circular loop is doubled, then magnetic flux linked with the circular loop will also become two times. Reason No flux will link through the coil by its own current.
