Milliammeter is which of the following?

Explanation:
A milliammeter is an instrument for measuring electrical current, but with the scale in milliamperes. The prefix milli- means one-thousandth, so it reads small currents in the mA range. An ammeter measures current in amperes, a voltmeter measures voltage, and an ohmmeter measures resistance. Because the milliammeter is marked in milliamperes, it’s the tool you use when the current in a circuit is small and expressed in mA.
