How many terminals are there in wattmeter?
Answers
Answer:
The two terminals of the current coil are denoted by M and L. M terminal is to be connected to the power supply and the L terminal is to be connected to the Load. The two terminals of the voltage or pressure coil are denoted by C and V.
Answer:
An electrical gauging tool called a wattmeter is used to gauge the power flowing through a circuit. It gauges the circuit's voltage plus current and shows how much current is being used.
The power metre usually has four terminals:
Two for measuring the circuit's voltage and two for measuring its current flow. While the current clamps are connected in series with the load, the voltage clamps are connected in parallel with the load being monitored.
Current terminals are typically designated "+A" and "-A," while voltage terminals are typically marked "+V" and "-V."
Current terminals are also known as power terminals and voltage terminals are also known as potential terminals.
Using the formula P=VI, where P is power, V is voltage, and I is current, the power being used by the circuit is calculated from the voltage and current readings made by the wattmeter.
In order to measure the power being used by an electrical circuit, a wattmeter has four terminals: two for monitoring voltage and two for measuring current.
