  1. Practical Labs

  2. Alternating Current Impedance Three loads wired in series

  3. Alternating Current Impedance One resistive – a light One capacitive – a capacitor One Inductive – a motor

  4. Alternating Current Impedance Switches are added in parallel with the capacitor and motor. Closing a switch causes current to bypass the load

  5. Resistance Voltage and current are in phase in a resistive circuit. With both switches closed the current bypasses both the inductive and capacitive loads.

  6. 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.

  7. Capacitance Voltage peaks after current in a capacitive circuit. The capacitor becomes part of the circuit when its switch is opened adding capacitance to the circuit.

  8. 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.
