Description : How can we reverse the direction of rotation of synchronous motor?

Last Answer : By reversing supply phase sequence we can reverse the direction of rotation of synchronous motor.

Description : What happens when you reverse the direction of the current in an electromagnet?

Last Answer : When  you  reverse  current  direction  in  an  electromagnet,  the magnetic  poles  will  also  change.

Description : What is the difference between forward and reverse bias?

Last Answer : Forward bias is a PN junction bias which allows current to flow through the junction. Forward bias decreases the resistance of the depletion layer. Reverse bias is a PN junction bias that allows only ... Positive polarity on the n-type material and negative polarity to the p-type material.

Description : what is reverse power relay?

Last Answer : Thereverse powerrelay is a directional protective relay that prevents power from flowing in the reverse direction. Read our article going back ... it all to be up to date. And if you do, read it anyway just to check if youreallydo!

Last Answer : In cut-off region of BJT both the emitter-base junction and collector-base junction are reverse biased.
