Final answer:
The rms current flowing through a light bulb with an average power of 60 W, assuming a standard household voltage of 120 V, is 0.5 A.
Step-by-step explanation:
The question asks to calculate the rms current flowing through a light bulb that uses an average power of 60 watts (W). To solve for the rms (root mean square) current, we would use the formula P = Irms * Vrms, where P represents the average power, Irms is the rms current, and Vrms is the rms voltage. Since the average power is given as 60 W and a standard US household voltage is assumed to be 120 V, the formula can be rearranged to solve for Irms: Irms = P / Vrms. Substituting in the given values, Irms = 60 W / 120 V, we find that the rms current Irms is 0.5 A.
This calculation is relevant for alternating current (AC) circuits, like those typically found in households, and shows that the average or rms values are often used in practical situations to describe electrical properties.
