Question
State Ohm's Law. Represent it mathematically.
Advertisements
Solution
According to Ohm's law, "Electric current through a metallic conductor is directly proportional to potential difference across the conductor of the circuit provided that temperature remains constant."
Mathematical expression for Ohm's Law: I ∝ V.
Or V = IR
Or I = `"V"/"R"`
Where, R = constant called resistance of a given metal.

The circuit depicted in the figure is employed for studying Ohm’s Law. Instead of using a standard resistor, a student opts for a glass tube filled with mercury (tube 1), connected to the circuit through two electrodes, E1 and E2. He records the readings of the ammeter and voltmeter, thereby calculating the resistance. The student repeats the experiment by substituting tube 1 with tube 2, where the same amount of mercury fills tube 2.
Neglecting internal resistance of the cell use (> or < or =) to compare:
- the resistance in both the cases.
- the voltmeter readings in both the cases.
- the specific resistance in both the cases.
