Why voltage in transformer suddenly increases and then decreases suddenly?
In perfect condition, the voltage variations does not occur.. Due to failure causes, voltage variations will arise
Why is a motor rated in KW's and a transformer rated in KVA?
One reason is that the motor is expected to do work (watts) whereas a transformer only changes the voltage and (ideally) does no work. [Yes, losses do occur.]
What is a threshold voltage in scr?
the voltage at which the current conduction occur
How did Stephen hawking's accident occur?
Stephen Hawking did not have an accident. When he was in college he was diagnosed with motor neurone disease which led to his current condition.
Can you start 20kw motor on direct on line circuit?
No, the motor has to be connected to the line voltage through a set of fuses and then an electrical contactor. Also the motor must be thermally protected against overloads by using an overload block or heaters. This is to allow the motor contactor to drop out is a overload fault should occur.
Effect of under voltage on induction motor?
if it is a three phase motor it can be run an the single phase mains but it woild require a hand start in either direction, if you put a capacitor on line two and three and the live and neutral on line one and two then it should work
Why would an induced over voltage occur and what damage may occur if this happened while working on an unprotected computer?
Why would an induced over voltage occur and what damage may occur if this happend while working on an unprotected computer?
What is the advantage of using two phase in single phase motor?
Two phase motors are a thing of the past and are not used today if any still exist. Two phase legs are classified as a single phase system. If the question refers to a dual voltage motor then the answer depends upon what supply voltages are available to operate the motor. Operating a motor at the higher of the two voltages means that smaller control equipment and wire feeders can be used to operate the motor. If the nameplate is checked, in the amperage box there will be two current ratings, Amps/Amps. One will be half of the other one. Look at the supply voltage box and you will see the corresponding Voltage/Voltage. The first number in the voltage box corresponds to the first number in the amperage box. The higher the voltage the less line loss will occur over a distance. If possible always try and use the highest voltage to operate motors.
What is open post voltage?
The open post voltage in electronics is the maximum voltage available from a solar cell. This will occur at zero current.
What happens if you place a capacitor on a dc motor?
Depending on voltage and amperage needed to run the motor,say,3volts.If you use a 3+volt capacitor what will happen is that the motor will turn once(not rev/min) and stop when the capacitor is completely drained which would occur in about half a second or less. Contributed writer:Dennis Wachira.
What does it mean if a cell has positive voltage?
The reaction will occur naturally
How is an electrooculogram recorded?
by the voltage changes that occur as eye position changes.
