Did you know?
WebWhat is the current in the resistor? Using Ohm's Law, i = v/R gives us i = (A sin wt) / R. So when the voltage is a sinusoid, the current is a sinusoid, too. In general, if you define either v or i to be sinusoidal, the other will follow along and be sinusoidal, too. In a resistor, the sinusoidal i and v are lined up with each other in time.
