Alternating Current Impedance
One resistive – a lightOne capacitive – a capacitorOne Inductive – a motor
Alternating Current Impedance
Switches are added in parallel with the capacitor and motor. Closing a switch causes current to bypass the load
Resistance
With both switches closed the current bypasses both the inductive and capacitive loads.
Voltage and current are in phase in a resistive circuit.
Inductance
Voltage peaks before current in an inductive circuit.
The motor becomes part of the circuit when its switch is opened – adding inductance to the circuit.
Capacitance
The capacitor becomes part of the circuit when its switch is opened adding capacitance to the circuit.
Voltage peaks after current in a capacitive circuit.
Inductance & Capacitance
Voltage and current are in phase in a circuit with capacitance offsetting inductance
Both the capacitor and the motor becomes part of the circuit when their switches are opened.
