Basic Electrical Engineering-Set 2

KCL deals with the conservation of:

• Momentum

• Mass

• Potential Energy

• Charge

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

• Current is reduced to half its original value

• Current is increased to double its original value

• No change

KWh is a unit of:

• Power

• Energy

• Efficiency

Which theorem helps analyze a circuit that has more than one active power sources

• Superposition theorem

• Reciprocity theorem

• Maximum Power Transfer Theorem

• Thevenin's theorem

In Reciprocity theorem, we consider ratio of response to excitation as ratio of

• Voltage to voltage

• Current to current

• Current to voltage

• Voltage to current

Superposition theorem is valid for

• Linear circuits

• Non-linear circuits

• Both linear and non linear circuits

If source impedance is complex, then maximum power transfer occurs when the load impedance is _______ the source impedance.

• Equal

• Negative

• Negative Complex Conjugate

• Complex conjugate

Superposition theorem is suitable for:

• Power calculation

• Voltage calculation

• Current calculation

• Both voltage and current calculation

Iron loss, core loss or no load loss in transformers are determined by conducting:

• Open circuit test

• Short circuit test

Nodal analysis can be applied for non-planar networks also.

• True

• False
