GENERAL ELECT ENGG

When an additional resistor is connected across an existing parallel circuit, the total resistance??

• Remains the same

• Decreases by the value of the added resistor

• Increases by the value of the added resistor

• Decreases

In a Y-connected circuit, the magnitude of each line current is ?

• One-third the phase current

• Three times the corresponding phase current

• Equal to the corresponding phase current

• Two times the corresponding phase current

In a balanced three-phase load, each phase has

• An equal amount of power

• One-third of total power

• Two-thirds of total power

• A power consumption equal to IL

The percentage slip in case of a synchronous machine is ?

• 1%

• 100%

• 0.5%

• zero

Specific resistance of Conductor will vary according to the temperature??

• Remains constant as Specific resistance is intrinsic quality of material

• Increases with increase in temperature

• Decreases with increase in temperature

• Increase with decrease in temperature

In case of No load, secondary winding of CT should be kept ?

• Open

• Close

• Shorted

• Depends on No load Voltage

For 11 KV Power transformer rating of LA is
