Wattmeter
Clamp meter
It is an instrument used to measure the amount of electrical current intensity in a circuit. The unit of measure is ampere. It is connected along or series to the circuit.
It is an instrument used to measure electrical pressure or voltage of a circuit. The unit of measure is volt. This is connected across or parallel to the circuit.
It is an instrument for measuring electrical resistance and is used to test the continuity of conductors.
It is used to measure the voltage, resistance and current of a circuit. It is connected in parallel or series with the circuit depending on what to measure.
Current measurements of a circuit are valuable because the reading indicates the amount of work being performed.
