CBSE Class 12-science Physics Semiconductor Electronics
Application of a voltage across the diode is called biasing.
A diode allows current to flow in the forward biased condition and does not allow any current to flow in the reverse biased condition.
PN junction diodes offer low resistance in forward bias and high resistance in reverse bias.
Diode rectify an ac by allowing the current to flow only in one direction.
Zener diodes are used for voltage regulation.
Solar cells convert photon energy into electricity.
