Consider a circuit driven by a 110~V110 V ideal battery and dissipating a total of 1200~W1200 W of power. What is the total current supplied by the battery?

Answer : The total current supplied by the battery is, 10.9 A

Explanation :

The relation between power, voltage and current is:

where,

P = power of circuit = 1200 W

I = current = ?

V = voltage = 110 V

Now put all the given values in the above formula, we get the total current supplied by the battery.

Thus, the total current supplied by the battery is, 10.9 A
