Electronics - Alternating Current and Voltage - Discussion

Because the center lines value is 6v that is why dc voltage is 6v.

Take the average value of all the given values to get dc voltage.

AC is changing from 2 to 10, but dc as we know has to be constant, so it has to be in the middle to achieve the same result.

Can anyone help me to get it?

What is the "average" and "effective" value of 2A DC current?

Please explain how to find that?

Please anyone explain in detail still I'm not understand.

The term RMS stands for root mean square. Most AC voltmeters display RMS voltage. The
120 V at your wall outlet is an RMS value. The RMS value, also referred to as the effective
value, of a sinusoidal voltage is actually a measure of the heating effect of the sine wave.

For example, when a resistor is connected across an AC (sinusoidal) voltage source, a certain amount of heat is generated by the power in the resistor. The value of the DC voltage can be adjusted so that the resistor gives off the same amount of heat as it does when connected to the AC source.

The RMS value of a sinusoidal voltage is equal to the DC voltage that produces the
same amount of heat in a resistance as does the sinusoidal voltage.

Average value of sine wave is zero observe the waveform at zero 6v is there.

As per above the circuit it's sine wave, we can find peak to peak value but dc value how? one more example please.

Average value is zero for sine wave.

But for the given waveform they clamped DC level to 6V.

So answer is 6V.
