Final answer:
The power of the light bulb with a voltage of 120 volts and a current of 0.625 amperes is initially calculated as 75 watts. However, taking into account the average current over time due to AC power, the real power of the light bulb is 60 watts.
Step-by-step explanation:
To calculate the power of a light bulb with a voltage of 120 volts and current of 0.625 amperes, you can use the formula for electric power =P = IV=, where =P= is the power in watts, =I= is the current in amperes, and =V= is the voltage in volts. In this case, the power would be =P = (0.625 amperes) * (120 volts)=, which equals 75 watts. However, considering the average current provided over a period of time is actually 0.50 A due to the alternating current (AC) nature of household power, the correct calculation should be =P = (0.50 amperes) * (120 volts)=, which results in a light bulb of 60 watts.
