What Are Wattmeters?
Wattmeters are instruments specifically designed to measure electrical power, expressed in watts, within an electrical circuit. They play a vital role in both monitoring and managing power usage.
These devices have the capability to simultaneously measure both voltage and current. Since the power in a circuit is calculated by multiplying voltage and current, wattmeters use these measured values to accurately determine the wattage. Their applications are varied, extending from household to industrial uses. In residential settings, wattmeters are commonly used to track the amount of electrical power consumed. In industrial environments, such as power plants and factories, they are essential for monitoring power consumption, helping to control and reduce unnecessary power wastage.
