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 

Answer:

Current, I = 0.029 A

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

[tex]I=\dfrac{P}{V}[/tex]

[tex]I=\dfrac{3.5\ W}{120\ V}[/tex]

I = 0.029 A

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