Characteristics of alternating currents — practice question
A student is working with a power supply whose output is sinusoidal. The meters on the supply indicate that the output voltage $V$ has a root-mean-square (r.m.s.) value of $14\,\text{V}$ and a frequency of $750\,\text{Hz}$. The way the output voltage $V$ changes with time $t$ can be written as $V = V_0 \sin \omega t$.
