10F-ELENGR115A-1 Quizzes QUIZ3 Attempt 1 1 Marks: 1 Choose one answer. a. 13.5 b. 27 c. 9 d. 3/4 In the circuit shown below, sw1 has been closed for a long time at t=0s the sw1 opens and sw2 connects the capacitor to a resistor. Find the total energy dissipated on resistor. (note that the capacitor is nonlinear and the Q vs V is shown in the picture). 2 Marks: 1 Choose one answer. a. 2 b. 1 c. 0.5 d. 0 In this circuit in left voltage source has been at +2V for a long time at t=0s the voltage of this source changes as a step to -2.7V while the right voltage source changes from -2.7 to +2.7. What is the final voltage on the capacitor D,ON =0.7V and τ T =100pS, also the diode depletion capacitance in reverse bias is much less than C) 3 Marks: 1 The I-V characteristics of a tunnel diode are given by:- I = I 0 + a 1 (V – 250mV) + a 3 (V – 250mV) 3 where I 0 = 2.03125mA, a 1 = -7.5x10
