Question

An unknown circuit draws a current of 2A from a 12V battery. Its equivalent resistance is

A)

24 Ω

B)

6 Ω

C)

12 Ω

D)

2 Ω​

Answer 1

Answer:

B) 6ohm

Explanation:

R

= v/i

R = 12/2

R = 2

Answer 2

Answer:

Equivalent resistance is 6 Ω.

Explanation:

Given :-

Voltage = 12 V

Current = 2 A

To find :-

Equivalent resistance

Solution :-

Using Ohm's law,

$V = IR$

$R = \frac{V}{I}$

• $R = \frac{12}{2}$

• $R = 6$

∴ Equivalent resistance is 6 Ω.
