Voltage after which in forward bias current start to rise with increase in voltage is called:

Correct answer: D. Knee voltage

  • A. Breakdown voltage
  • B. Reverse voltage
  • C. Forward voltage
  • D. Knee voltage

Explanation

Knee voltage is the forward voltage at which the flow of the current through the PN junction of the diode increases rapidly. The knee voltage is generally observed in Zener Diodes.The forward voltage at which current starts to rise with increase in voltage is called 'knee voltage'.

About Alternating Current

Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
