WebSo then, for two ohm resistor to calculate the current here, I would substitute R as two, V is 50, calculate the current. Then for 40 Ohm resistor, I would put V is 50, that's already given, R is 40. Calculate the current, same thing over here. And we are done. We now know current through each resistor. But do you understand, that's wrong. 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.
