A nightlight uses 4.00 W of power when plugged into an outlet. Assume that the only resistance in the circuit is provided by the light bulb's filament. The current in the circuit is 3.40 X 10^-2 A. What is the voltage across the filament?

Respuesta :

Answer:

117.6 v

Explanation:

4 watts = V * 3.4 x 10^-2

  V = 117.6 V
