Answer:
kVA units.
Step-by-step explanation:
Given : In a parallel circuit et= 240 v ,r = 30 ohms and xl = 40 ohms.
To find : What is the power factor?
Solution :
In a parallel rl circuit we have,
Total voltage, et= 240 Volts,
Resistance, r= 30 ohm,
Inductive Reactance, xl= 40 ohm.
In parallel circuit, the voltage across resistor and inductor remains same.
i.e. vr = vl= v= 240 Volts
Using Ohm's Law,
The current across resistor would be
Using Ohm's Law,
The current across inductor would be
Now, Total current would be
The voltage is 240 V and current is A= 10 amp
The power factor is
kVA units.
