6.24.1 In the circuit below, all the capacitors have already reached steady state (no current flowing through the capacitors). Determine the voltage across capacitor C5, if C = 27 UF , C2 = 24 UF , C3 = 11 UF , C4 = 14 UF , and C5= 13 UF. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and the proper SI unit. C2 C4 15 mA 10 k2 C3 C5 Your Answer: Answer units

6.24.2 In the circuit below, all the capacitors have already reached steady state (no current flowing through the capacitors). Determine the energy (in mJ) stored in capacitor C5, if C₁ = 12 μF, C₂ = 20 μF, C3= 25 μF, C₁ = 23 μF, and C5= 10 μF. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. 15 mA Your Answer: 10 ΚΩ C₁ C₂ C3 CA C5

TRUE or FALSE a. A discontinuous change in the voltage requires an infinite current thus a capacitor resists an abrupt change in the voltage across it. b. The inductor takes power from the circuit when storing energy and delivers power to the circuit when returning previously stored energy.

A source-free RC circuit contains a 1 ohm resistor and a 10 mH inductor initially charged to 1 Ampere. How much time is needed for the current across the inductor to decay to 0.368 amperes? Enter your answer in seconds.

You wish to build a time delay circuit using an RL circuit, and the resistance in the circuit is 110 ohms. You want the voltage across the inductor to fall to 0.1V from an inital voltage of 1.5V in a period of 0.1s. What must the inductance of the inductor be? a. -164Hb. 3.0Hc. 40Hd. 11He. 4.1H.

An AC bridge circuit the supply voltage is 20 V at 500 Hz. Arm AB is 0.25 µF pure capacitance; arm BD is 400 0 pure resistance and arm AC has a 120 Q resistance in parallel with a 0.15 µF capacitor. Find resistance and inductance or capacitance of the arm CD considering it as a series circuit

A 10¯7-F capacitor (100 nanofarads) is charged to 100 V and then disconnected. One can model the charge leakage of the capacitor with a RC circuit with no voltage source and the resistance of the air between the capacitor plates. On a cold dry day, the resistance of the air gap is 3× 103 Q; on a humid day, the resistance is 8 x 10° Q. How long will it take the capacitor voltage to dissipate to half its original value on each day?
