Description : How does AC current change direction?
Answer : This is because the angle at which the magnetic fields cuts across a winding changes its poles thus current has to change dirention .
Description : What happens when you reverse the direction of the current in an electromagnet?
Answer : When you reverse current direction in an electromagnet, the magnetic poles will also change.
Description : What is the direction of flow of electric current in an electric circuit?
Answer : It flows from anode to cathode (direction of holes flow)
Description : The direction of rotation of an inverter fed 3-phase ac motor is reversed by (A) a mechanical reversing switch (B) reversing the input dc link voltage (C) operating the inverter as a rectifier (D) changing the sequence of switching
Answer : The direction of rotation of an inverter fed 3-phase ac motor is reversed by changing the sequence of switching
Description : What is the direction of the induced current?
