How does forward biasing affect the conduction of a thyristor?
Forward biasing decreases the resistance of the thyristor, allowing it to conduct current.
Forward biasing causes the thyristor to switch off completely.
Forward biasing has no effect on the conduction of the thyristor.
Forward biasing increases the resistance of the thyristor, preventing it from conducting current.
