The alternating current which crosses an apparatus of 600 W has a maximum value of 2.5 A. What is efficient voltage between its demarcations? A. 140 V
B. 240 V
C. 340 V
D. Impossible to find without knowing the resistance of the apparatus

Respuesta :

Answer: Option (b) is correct.

Explanation:

Since we know that,

P = VI

where;

P = power

V= Voltage

I = Current

Since it's given that,

P = 600W

I = 2.5 A

equating these values in the above equation, we get;

V = [tex]\frac{600}{2.5}[/tex]

V = 240 V
