Model
1. Circuit A: A sinusoidal voltage of constant amplitude V0 = 3V and varying frequency is applied across a 100 ohm resistor and a 2.2 µF capacitor in series.
2. Calculate τ = RC and ω1 = 1/RC for this circuit and the fill in the table.
τ = ________s ω1 = ________rad/s f1= ________Hz
ω/ω1 Frequency (cycles/s=Hz) Frequency (radian/s) XC (Ω) R (Ω) I = V0 / √(XC^2 + R^2) VC = IXC VR = IR
