Question

Draw a labeled diagram of the experiment explaining Ohm's law.

Answer 1

Ohm's Law states that the current flowing in a circuit is directly proportional to the applied potential difference and inversely proportional to the resistance in the circuit if physical condition remains same.

$\Rightarrow V=IR$

In Ohm's Law Experiment you will construct a simple circuit (As shown in figure) using a single known resistance, R. Then you will use an ammeter to measure the current, I, through the resistance and a voltmeter to measure the potential difference, V, across the resistance. With this data, you can check the validity of Ohm's Law (V = IR) in the circuit.
