How many kilowatt-hours (kWh) would a power supply providing 60 volts and 10 amperes of current yield over 3.5 hours?

To calculate the total energy consumption in kilowatt-hours (kWh), you can use the formula:

Energy (kWh) = Voltage (V) × Current (A) × Time (h) / 1000

In this case, the voltage is 60 volts, the current is 10 amperes, and the time is 3.5 hours.

Now substituting the values into the formula:

Energy (kWh) = 60 V × 10 A × 3.5 h / 1000
Energy (kWh) = 600 V・A・h / 1000
Energy (kWh) = 0.6 kWh × 3.5
Energy (kWh) = 2.1 kWh

Thus, the power supply would yield 2.1 kilowatt-hours over the specified duration. This explanation highlights how to derive energy consumption based on voltage, current, and time, ensuring a clear understanding of the calculations involved.
