## FAQs on RMS Voltage Video Lecture - Physics Class 12 - NEET

 1. What does RMS voltage stand for?
Ans. RMS voltage stands for Root Mean Square voltage. It is a measure of the average voltage of an AC signal or waveform.
 2. How is RMS voltage calculated?
Ans. RMS voltage is calculated by taking the square root of the mean (average) of the squares of the instantaneous voltage values over one complete cycle of an AC signal.
 3. What is the significance of RMS voltage?
Ans. RMS voltage is significant because it represents the equivalent DC voltage that would produce the same amount of power dissipation in a resistive load as the AC voltage. It is commonly used to compare and measure the voltage levels of AC signals.
 4. How does RMS voltage differ from peak voltage?
Ans. RMS voltage is a measure of the average voltage of an AC signal, while peak voltage represents the highest voltage value reached by the signal. RMS voltage takes into account the varying voltage levels over a complete cycle, whereas peak voltage only considers the highest point.
 5. Why is RMS voltage important in electrical applications?
Ans. RMS voltage is important in electrical applications because it helps in determining the power delivered by an AC source to a load. It allows accurate calculations for power consumption, current flow, and voltage drop in electrical circuits. By using RMS voltage, designers and engineers can ensure proper functioning and safety of electrical devices and systems.
