The appropriate question is: In an R-L circuit R= 3.5ohm & L= 100mh (0.1 H), if 50HZ, 220V is supplied to the circuit, what is the impedance, current & power factor ?
Acc to the question,
- R= 3.5 Ω
- L= 0.1 H
- Frequency = 50 Hz
- Voltage = 220 V
We know that,
Inductive reactance:
XL= 2πfL
= 2πx50x 0.1
= 31.416Ω
Impedance:
Z = √(R² + XL²)
= √(3.5² + 31.416²)
= 31.61Ω
Power factor:
For series PF = R/Z
= 3.5/31.61
= 0.1107
Current:
I = V/Z
= 220/31.610
= 6.95 A
