In an R-L circuit, the impedance is 30 Ω at a frequency of 100 Hz. At 200 Hz, the impedance should be
Answer: Option
Explanation:
Z = (R2 + ω2L2)0.5.
49.
In the circuit, Vs = 10 cos ωt, power drawn by the 4Ω resistor is 8 watt. The power factor is
Answer: Option
Explanation:
I2m = P/R 
Im = 2
Total power drawn
= 
I2R x 2 x [4 + 2] 6
VmIm cos θ = 6
x 10 x 2 x PF = 6 P.F = 0.85 .
50.
The electric energy required to raise the temperature of a given amount of water is 1000 kWh. If heat losses are 25%, the total heating energy required is __________ kWh.
Answer: Option
Explanation:
Total heating energy required = 1000 kWh + 25% of 1000 kWh.
