This circuit represents the relationship between Voltage and Current in series inductive/capacitive circuits.
Top right: Resistor
V&I are in phase.
2nd Top right: Resistor + Capacitor
I lags V by ~90 degrees
2nd Bottom right: Resistor + Inductor
V lags I by ~90 degrees
Bottom Right: V&I are in phase
By adjusting L & C to
resonance, V&I are in phase.
Fr = 1/(2*Pi*sqr(L*C))
50hz = 1/(2*Pi*sqr(10mH*1mF))
