Question

experimental verification of jules law​

Answer 1

the about relations are experimentally verified by jeweled and are known asJules law of heating my equation -Jules law implies that the heat produced is directly proportional to the square of the current for a given R it is directly proportional to the resistance R.

Answer 2

ANSWER

Joule’s law is verified using Joule’s calorimeter. It consists of a resistance coil R enclosed inside a copper calorimeter.

The ends of the coil are connected to two terminals, fixed to the lid of the calorimeter. A stirrer and a thermometer T are inserted through two holes in the lid. Two thirds of the volume of the calorimeter is filled with water. The calorimeter is enclosed in a wooden box to minimise loss of heat.

A battery (Bt), a key (K), a rheostat (Rh) and an ammeter (A) are connected in series with the calorimeter. A voltmeter (V) is connected across the ends of the coil R.
