Quantity	Units	Measuring Instrument	What Is It
Current	Amps or Amperes	Ammeter or multimeter	A flow of charged particles (usually electrons)
Voltage	Volts	Volt Meter or multimeter	The electromotive force that causes current to flow
Resistance	Ohms	Ohm meter or multimeter Ammeter + Voltmeter	Resistance restricts the flow of current to a lower level Ohms = Volts / Amps
Power	Watts	Ammeter + Voltmeter	Volts x Amps
Energy	Joules	Ammeter + Voltmeter + Clock	Volts x Amps x Seconds
Capacitance	Farads	Capacitance meter or some multimeters	The ability to store charge (like water bucket size)
Charge	Coulombs	Ammeter + Clock	Amps x Seconds
Frequency	Hertz	Frequency Meter or some multimeters	This counts the number of cycles of a wave per second.
Time	Seconds	Clock or Oscilloscope	Ask Stephen Hawking!
