Question

The figure below shows three lightbulbs connected to a 120-V AC (rms) household supply voltage. Bulbs 1 and 2 have a power rating of 95 W, and bulb 3 has a 45-W rating.

(a) Find the rms current in each bulb.

I_{bulb 1}	=
I_{bulb 2}	=
I_{bulb 3}	=

(b) Find the resistance of each bulb.

R_{bulb 1}	=
R_{bulb 2}	=
R_{bulb 3}	=
