Question

When 4 cells of 1.5 volt each are applied in a circuit a current of 1.2 A flows through it calculate the resistance of the circuit

Answer 1

Answer:

Explanation:

Given:

Potential Difference V= 1.5V * 4 = 60V

Current I =  1.2A

By Ohm's Law : V= I*R

=> R = V/I

∴ R = 60V / 1.2A

      = 50 ohms. Ans.

Answer 2

Answer:

Resistance = 5 Ohm

Explanation:

Given : Current (I) = 1.2 A

Voltage (v) = 4*1.5 = 6.0 v

To find : Resistance (R)

By Ohm's law :-

V = I × R

6 = 1.2 × R

R = 6.0 / 1.2

R = 5 Ohm.
