The electrical energy required to heat a bucket of water to a certain temperature is 2 kWh. If heat losses, are 25%, the energy input is
Answer: Option
Explanation:
Since 25% of input is lost, 0.75 Input = 2 or input = 
38.
The circuit in figure will act as ideal current source with respect to terminals A and B when frequency is
Answer: Option
Explanation:
When ω = 4 rad/sec ωL and 
are equal.

The current rating of a cable depends on
Answer: Option
Explanation:
Current rating depends only on area of cross-section and hence diameter.
40.
In an ac circuit, the maximum and minimum values of power factor can be
Answer: Option
Explanation:
Power factor is maximum and equal to 1 for purely resistive load. Power factor is minimum and equal to zero for purely reactive load.
