Answer

The RMS of a wave is directly proportional to the energy carried by the wave.

Root Mean Square (RMS) of a wave is a measure of the average power of the wave.
The higher the RMS value of a wave, the more energy it carries.
RMS value is calculated by taking the square root of the average of the square of the values of the waveform.
For example, in electrical engineering, the RMS value of an AC voltage or current wave determines the power dissipated in a resistor.

Feedback control in a circuit involves using control relays to regulate the system's output based on input signals.

Feedback control involves comparing the actual output of a system to a desired reference signal and adjusting the system's operation accordingly.
Control relays are used to switch electrical circuits on or off based on the input signals received.
Thevenin's theorem can be applied to simplify complex circuits into equivalent circuits for analysis and design.
