Transcript of Phys 272 Alternating Current. A.C. Versus D.C (Natural) Frequency, Period, etc…
The Rule1. Replace the voltage by complex version.2. Use Ohm’s law to find the complex current.
Pretend R, L, C are all resistors with complex reactance.
3. The imaginary part of the complex current gives you the real current I(t).
4. The magnitude of the complex current gives you the amplitude of the real current.
