You have a nightlight plugged into an outlet in the hallway, which uses 3.5 watts when plugged in. If the house circuit provides 120.0 volts, what is the current through this bulb?

Answer:

Current, I = 0.029 A

Step-by-step explanation:

It is given that,

Power of the nightlight plug, P = 3.5 watts

The voltage provided by the house circuit,V = 120 volts

We know that the power of an electrical appliance is given by :

Power = voltage × current


I=(P)/(V)


I=(3.5\ W)/(120\ V)

I = 0.029 A

Hence, the current through this bulb is 0.029 A. Hence, this is the required solution.

Base on the said question or problem that state and ask to calculate the current of the said light bulb and in my further calculation and further analysis, I would say that the current of the light bulb would be 0.0292. I hope you are satisfied with my answer and feel free to ask for more
