Question

how will you show experimentally that when the amount of current is increased through a conductor it produces more heat

Answer 1

not only current should be high for that ........high voltage and high resistance is needed ......for example an a heater due to large resistance produces heat

Answer 2

Answer:

In fact, for most conductors it can be shown experimentally that the current flowing through it, I, is directly proportional to the pd across it V. So, for a particular conductor V/I is a constant, and this constant is called the resistance of the conductor, R, such that R = V/I.
