what is Multimeter?

Multimeter: In practice, measurements

of current and potential difference are

made with a digital multimeter that can

switch between functioning as an ammeter

and functioning as a voltmeter. It displays 

the results with an auto-ranging numerical

digital display, which includes the sign of

the potential difference or current. Most

digital multimeters can also measure the

resistance of a circuit component; that is,

they can function as an ohmmeter.
