Voltage . . . DC voltmeter
Current . . . DC ammeter
The "ohmmeter" is also fundamentally a DC ammeter at heart.
Frequency . . . DC doesn't have frequency.
An ammeter. It measures the electrical current output.
An instrument that measures electric current in amperes.
an 'ammeter'
A multimeter can measure direct current voltage (VDC) by selecting the appropriate setting on the device and connecting the probes to the circuit.
A thermometer is sufficient.
galvanometer
An ammeter is the instrument that measures electric current in a circuit. It is connected in series to the circuit to measure the flow of current through it.
It measures the current.
A galvanometer is a type of ammeter: An instrument for detecting and measuring electric current.
An ammeter is the instrument used to measure current in an electric circuit. It is connected in series in the circuit and provides a reading of the amount of electric current flowing through it.
A multimeter can measure different things related to electricity, including current and voltage.
A compass can be used to measure the direction of current flow in a circuit by aligning the compass needle with the magnetic field created by the current.
