Question

In the given electric circuit if the current flowing through 3 ohm resistor is 1 A,find the voltage of the battery and current I drawn through it.

Answer 1

Answer: 3 V, 1 A

Explanation:

From Ohm's law, the electric current flowing in the circuit is directly proportional to the potential difference across the conductor.

I ∝ V

V = I R

Where, R is the resistance.

It is given that, R = 3 Ω

I = 1 A

Thus, V = I R  ⇒ V = 1 A × 3 Ω = 3 V

In the given electric circuit if the current flowing through 3 ohm resistor is 1 A, the voltage of the battery = 3 V

The current drawn through it would be 1 A.
