Which tool can be utilized to test the electrical power of a computer?

The correct tool for testing the electrical power of a computer is the multimeter. A multimeter is an essential diagnostic instrument that can measure various electrical quantities, including voltage, current, and resistance. When testing the electrical power of a computer, the multimeter allows you to check the output voltage from the power supply or measure the current flowing through the circuits. This capability is crucial for troubleshooting power-related issues in computers, such as verifying whether the components are receiving the correct voltage needed to operate effectively.

While a voltmeter is specifically designed to measure voltage, its usability is somewhat limited compared to a multimeter, which combines the functions of a voltmeter, ammeter, and ohmmeter. A screwdriver is useful for assembling or disassembling components, but it does not measure electrical characteristics. An ohmmeter, on the other hand, is focused solely on measuring resistance and would not provide the complete information needed to assess electrical power in a computer. Thus, the versatility and comprehensive functionality of the multimeter make it the preferred tool for testing electrical power in a computer system.
