Tabular column:
Type of load Voltage Current (I) Power factor (cos j) PF observation
(V)
Resistive 230 V 1 Amp 1 1 (Unity) Ideal
Inductive 230 V 1.5 Amp 0.5 0.5 lagging Poor
Inductive + capacitive 230 V 1.2 Amp 0.8 0.8 lagging
(1 capacitor parallel with load)
Inductive + capacitive 230 V 1 Amp 1 1 (Unity) Ideal
(2 capacitors parallel with load)
Inductive + capacitive 230 V 1.3 Amp 0.8 0.8 leading
(4 capacitors parallel with load) Over excited
Safety precautions:
1 Do not make wrong and loose connections.
2 Do not connect higher value and more No. of capacitors which causes high current in the circuit.
3 Do not touch the capacitor terminals without discharging.
4 Take the meter reading correctly.
