What are the maximum values of the following when an incandescent 55-W light bulb (at 110 V) is connected to a wall plug labeled 110 V?
P = VI
I = P/V = 55 / 110 = 0.5Amps.
R = V/I = 110 / 0.5 = 220 Ohms = Resistance of the bulb.
I = P/V = 55 / 110 = 0.5Amps.
R = V/I = 110 / 0.5 = 220 Ohms = Resistance of the bulb.
