Answer is Wrong!
Answer is Right!
The correct answer is: E. all of the above
Various adjustments in an energy meter include:
- Light load or friction: This is the adjustment that compensates for the small amount of power that is always drawn by the meter, even when there is no load on the circuit.
- Lag and creep: These are adjustments that compensate for the small amount of time it takes for the meter to start registering power when the load is applied, and for the small amount of time it takes for the meter to stop registering power when the load is removed.
- Overload and voltage compensation: These are adjustments that compensate for the fact that the meter may read slightly differently at different loads and voltages.
- Temperature compensation: This is an adjustment that compensates for the fact that the meter may read slightly differently at different temperatures.
All of these adjustments are necessary to ensure that the meter reads accurately.
