Question

you are trying to troubleshoot a desktop power supply issue using a voltmeter. which of the following options are the most common voltages produced by power - supplies? (select two)
□ + / - 110 v
□ + / - 10 v
□ + / - 5 v
□ + / - 12 v
□ + / - 120 v

Explanation:

Step1: Recall common power - supply voltages

Desktop power supplies commonly produce +5 V and +12 V. These are used to power different components in a computer. +5 V is often used for logic circuits and some peripherals, and +12 V is used for components like hard - disk drives, fans, and some expansion cards.

Step2: Eliminate non - common voltages

+110 V and +120 V are typical household AC voltages, not common DC voltages produced by desktop power supplies. +10 V is not a standard voltage produced by most desktop power supplies.

Answer:

+5 V, +12 V
