Who invented the multimeter?

1 Answer

The multimeter was invented by Donald Macadie, a British electrical engineer, in 1922. He created the device to combine several measurement tools—such as voltmeter, ammeter, and ohmmeter—into one compact device. This innovation made it much easier for electricians and engineers to measure voltage, current, and resistance without needing separate instruments for each. The multimeter has since become an essential tool in electrical and electronics work.
