An AC generator causes 50 Hz current in a circuit containing a 290 Ω resistor, 4.89 µF capacitor, 0.362 H inductor, and switch in series. At time t=0, the switch is closed at an instant when the voltage from the generator is 0 V. We measure the rms current as 41.1 mA. a) Write an expression for the instantaneous voltage (aka, the voltage as a function of time). v(t) = ______ b) Does the voltage lead or lag the current? Explain how you know.  c) Draw a phasor diagram at an instant when the current is zero. Label the phase angle. d) Draw a phasor diagram at an instant when the current is maximum. Label the phase ang
