The sum of all the voltages over any closed loop is equal to

What is the basic law used to analyze any circuit

In superposition theorem, when we consider the effect of one voltage source, all the other voltage sources are:

Thevenin's voltage is the:

Norton's current is the:

Maximum power is transferred from the source to the load when:

Short circuit test in transformers are used to identify

What happens to the current in a series circuit if the resistance is doubled?

KWh is unit of

An autotransformer has only one winding on its core.

The power dissipated as heat in the primary and secondary windings of a transformer due to its winding resistance is called copper loss because:

Losses in the transformer due to alternating flux in the core is called:

Core loss in transformers are also called:

Hysteresis loss is caused due to magnetization and demagnetization in the transformer core.

Iron loss comprises of:

kVA represents the apparent power of an electrical system.

Actual power, kW is defined as:

For DC Circuits kVA and kW are equal because

Power factor is the measure of how effectively the incoming power is used in the electrical system.

__________ is defined as the cosine of the angle between voltage and current

Which among the following are inductive loads:

(choose all that apply)

The theorem used for analyzing electric circuits that contains two or more active sources is:

Capacitive loads have leading power factor because

For an incandescent lamp the power factor is:

Inductive loads have:
