Q7.For the Zener diode shown in the figure, the Zener voltage at knee is 7 V, the
knee current is negligible and the Zener dynamic resistance is 10 Ω. If the input
voltage (Vi) range is from 10 to 16 V, the output voltage (V0) ranges from
Q9.In the following circuit, the switch S is closed at t = 0. The rate of change of
current is given by
Answer : Option BExplaination / Solution:
Initially i(0-) = 0 therefore due to inductor i(0+) = 0. Thus all current Is will
flow Is in resistor R and voltage across resistor will be IsRs. The voltage across
inductor will be equal to voltage across Rs as no current flow through R.
