What is the difference between energy Metre and wattmeter?
Answers
Answer:
The energy meter measures the total energy consumed by the load while the wattmeter measures the power in a circuit. The energy meter measures the energy in joules but wattmeter the measure the power in watts.
Answer:
The energy meter measures the total energy consumed by the load while the wattmeter measures the power in a circuit.
The energy meter measures the energy in joules but wattmeter the measure the power in watts.
The energy meter driving, braking, and moving system along with the counting mechanism are the main parts, but the wattmeter pressure and current coil, control system, scale and pointer, damping system to the central part.
The energy meter work on the principle of conversion of electrical energy into mechanical energy. Whereas the wattmeter works on the principle that the force acts on the current-carrying conductor when it is placed in an electromagnetic field.
