Question

6. (15 points) A circuit diagram is shown in the above figure (eft). The capacitors have the following capacitance values C 7 F and C2 10F. The resistors have the following resistance values R1 7m and R 102. (a) (4 points) Determine the equivalent capacitance in the circuit. (Reduce the problem to a single capacitor.) (b) (5 points) Determine the equivalent resistance in the circuit. (Reduce the problem to a single resistor.) (e) (2 points) Determine the time constant of the RC circuit. (d) (4 points) After some time the capacitor is charged and current is no longer flowing. The battery has a voltage rating of 24 V. Determine the charge on the capacitor.

Explanation / Answer

a) Equivalent capacitance= 17 F

b) Equi Resistance= ( 7 x 10) /17 = 4.177 ohms apprx

c) time constant = RC = 4.177 x17= 70

d)Q = CV = 17 (24)= 408 C
