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 the relation known? How much heat will an instrument of 12W produce in one minute if it is connected to a battery of 12V?
OR
Explain with the help of a labelled circuit diagram how you will find the resistance of a combination of three resistors, or resistance R , R and R , joined in parallel. Also mention how you will connect the ammeter and the voltmeter in the circuit when measuring the current in the circuit and the potential difference across one of the three resistors of the combination.

this is called Joule's law of heating.
All materials offer resistance to the flow of current through them. So some external energy is required to make the current flow. This energy is provided by the battery. Some of this energy gets dissipated as heat energy, so the resistor becomes hot.
Work done in carrying a charge Q through a potential difference V is given as
Also, Q = I t
Using Ohm's law, V = I R
W = I 2 Rt
This work done in carrying the charge th
rough the wire appears as the heat produced. i.e., H = V I t = I 2 Rt.
this energy is dissipated as heat energy.
