Unformatted text preview: capacitor are again out ­of ­phase, but the voltage across the capacitor is not the same as the voltage across the resistor: V(t) = Vmaxcosωt I(t) = Imaxcosωt VC(t) = Vmaxsinωt Vmax/Imax = R 2 + 1 / ! 2C 2 8. The average power in an AC circuit is Pavg = Vrms I rms = I r2ms R = Vr2 s / R m 9. A ground is anything that can source or sink an effectively infinite amount of charge (current) as part of a circuit, or any s...
