Description : What is the direction of an AC current?
Answer : The magnitude and direction of alternating current is changes with respect to time. So for half cycle it is positive and for next half cycle it is negative.
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 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 the induced current?
Description : What is the direction of flow of current?
Answer : Current flows from anode to cathode(opposite direction to flow of electrons)
