Question21:-A conducting diode is reverse biased at time = 7, .A measurement of current through the diode is made at three different time instants along the positive time axis at t
ர 50ھ 7, . Select the correct statement about the diode current.
കണ്ണട current drops to zero at time t= 7, and continues as such at t = 7, and t= 7,
BeThe current reverses at t = 77, and reaches the reverse saturation current at time t = 7, where the interval 7, to 7, 15 called the transition time
वाह current drops to reverse saturation current at t = 7, and continues as such at time t = 7, and t= 77, where the interval 7, to 7; is called the storage time
ഉട current reverses at t = 7, and continues as such till t = = 1, where the interval 7; to 7: is called the transition
time
व then reaches the reverse saturation current at time
Correct Answer: Option-D
