An AC current is given by $I=495 \sin (9.43 t),$ with $I$ in $\mathrm{mA}$ and $t$ in ms. Find (a) the rms current and (b) the frequency in $\mathrm{Hz}$.
Suppose a current is given by the equation $I=1.80 \sin 210 t$ where $I$ is in amperes and $t$ in seconds. $(a)$ What is the frequency? (b) What is the rms value of the current? (c) If this is the current through a $24.0-\Omega$ resistor, write the equation that describes the voltage as a function of time.
