elect all of the following that correctly describe what a voltmeter and ammeter measure. Select all that apply: A voltmeter measures the potential difference (or voltage) across a circuit element. A voltmeter measures the potential difference (or voltage) passing through a circuit element. An ammeter measures the electric current passing through a circuit element. An ammeter measures the electric current across a circuit element.

A voltmeter measures the potential difference (or voltage) across a circuit element.

An ammeter measures the electric current across a circuit element.

Explanation:

This because a voltmeter is an electric device use to measure voltage or potential difference in a circuit. It is connected parallel to a device in the circuit. voltage is measure in volts.

An ammeter is an electric device that is use to measure currents in a circuit even to the smallest part of current. Current is measure in Ampere and ammeter is connected in direct series to a device in a circuit.

explanation:

v=uf/(u-f)
