Question

Determine e when I = 0.50 A and R = 12 W.

Answer 1

Answer:

The correct answer is "24 V".

Explanation:

The given values are:

Current,

I = 0.50 A

Resistance,

R = 12 W

As we know,

⇒ $I = 0.5\times (\frac{E}{2R})$

On substituting the given values, we get

⇒ $0.5= (\frac{E}{4\times 12} )$

⇒ $0.5= (\frac{E}{48} )$

⇒   $E=24 \ V$
