1. Voltage (V) is a measure of how much electrical energy is in a circuit. Most household circuits operate at 120 volts (120 V). Is this true of the computer?

no

Explanation:

The computer has a PSU(power supply unit )which is a hardware component of a computer that supplies all other components with power. The power supply converts the 120 volt AC (alternating current) into a steady low-voltage DC (direct current) usable by the computer.

parts in a PSU include

   A rectifier that converts AC (alternating current) into DC.

   A filter that smooths out the DC (direct current) coming from a rectifier.

   A transformer that controls the incoming voltage by stepping it up or down.

   A voltage regulator that controls the DC output, allowing the correct amount of power, volts or watts, to be supplied to other computer hardware.
