Explanation:
Detailed explanation-1: -A power meter is used to measure power readings. A voltmeter is used to measure the potential difference between two points in a circuit.
Detailed explanation-2: -Electricity is measured in Watts and kilowatts A Watt is the unit of electrical power equal to one ampere under the pressure of one volt. One Watt is a small amount of power.
Detailed explanation-3: -A Power Meter is one of the most useful and simple instruments to measure electrical power when no deeper analysis of the measured data is required. It measures the voltage (V) and current (A) and derives from these the most important power results.
