- Homework Statement
- The voltage across the terminals of an ac power supply varies with
time. The voltage amplitude is V = 45.0 V. What
are (a) the root-mean-square potential difference Vrms and (b) the average
potential difference Vav between the two terminals of the power supply?
- Relevant Equations
- Vmax= square root 2*Vrms
I know that the answer for A is 31.82. But when i look up B why is it zero? can someone explain please
