Assertion: In forward biasing current starts when minimum voltage of battery becomes equal to knee voltage
Reason: Upto knee voltage barrier potential of diode prevents the motion of holes and electrons.

Statement1: In forward biasing current starts when minimum voltage of battery becomes equal to knee voltage Statement2: Upto knee voltage barrier potential of diode prevents the motion of holes and electrons.

Assertion: In a transistor amplifier, the output voltage is always out of phase with the input voltage. Reason: The emitter base junction is reverse biased and the base collector junction is forward biased.
