Question

A simple electric circuit has 15 V battery and resister of 60 Ω. What will be the current in the

circuit

a) 0.4 A b) 0.25 A c) 4 A d) 2 A​

Answer 1

Answer:

b) 0.25 A

Explanation :

Given -

• Potential difference = 15 V
• Resistance, R= 60 Ω.

By using Ohm's law -

Current = potential difference (V) / Resistance (R)

I = V/R

→ I = 15/60

→ 0.25 A.

Therefore, the current in the circuit will be 0.25 A and the correct option is b) i.e. 0.25 A.

Answer 2

Given ,

Potential difference (v) = 15 v

Resistance (r) = 60 ohm

We know that ,

$\boxed{ \sf{V = IR \: \: \{ by \: ohm's \: law \}}}$

Thus ,

15 = I × R

I = 15/60

I = 0.25 Amp

Therefore ,

• The current is 0.25 Amp
