i have read that vrms is the same as equivalent dc voltage but i have also read that vav and vdc are same but vav and vrms is not same vrms of sinosoid is zero but vav of sinousoid is not zero where i am wrong?

VAV (Volts Alternating Current) refers to the voltage of an alternating current system, which constantly changes direction. VRMS (Voltage Root Mean Square) is the effective or average voltage of an alternating current system. VDC (Volts Direct Current) refers to the voltage of a direct current system, which flows in one direction.
VAV and VRMS voltages are typically measured using an oscilloscope, which displays the waveforms of the alternating current. VDC voltage can be measured using a voltmeter, which reads the direct voltage in a circuit.
VAV, VRMS, and VDC voltages are important in determining the power and efficiency of electrical systems. VAV and VRMS voltages are used to calculate the power in an alternating current system, while VDC voltage is used to calculate the power in a direct current system.
The type of voltage used in an electrical appliance depends on its design and function. Some appliances, such as computers and electronic devices, require a steady VDC voltage to operate properly. Others, like household appliances, can function with either VAV or VRMS voltages.
Yes, VAV, VRMS, and VDC voltages can be converted using electrical devices such as transformers, which can change the voltage level without changing the frequency. However, the conversion process may result in some energy loss.
