Basic Electrical Engineering-Internals

KVL and KCL deals with the conservation of

• Mass

• Momentum

• Charge

• Energy

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

• 1V

• 0V

• infinity

• Supply voltage

What is the basic law used to analyze any circuit

• Kirchhoff's laws

• Amperes's law

• Faraday's law

• Newton's law

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

• Undisturbed

• Shorted

• Opened

• Altered

Thevenin's voltage is the:

• Open circuited voltage

• Short circuited voltage

• Voltage across the load

• None of the above

Norton's current is the:

• Short circuit current

• Open circuit current

• None of the above

• Current through the load resistor

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

• Source and load impedances match

• Source and load elements are passive

• Source admittance matches with load impedance

• Source and load admittances match

Short circuit test in transformers are used to identify

• Copper losses

• Winding losses

• Current losses

• Voltage losses

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

• Current doubles

• Current is reduced to half of its original value

• No change

KWh is unit of

• Power

• Energy

• Variance

• Efficiency
