Compute the voltage drops across the resistor and capacitor

Reference no: EM13992483

A capacitor with C = 4.00 x 10^-5 F is connected as shown in the figure below with a resistor with R = 900 Ω and an emf source with µ = 21.0 V and negligible internal resistance. Initially, the capacitor is uncharged and the switch S is in position 1. The switch is then moved to position 2, so that the capacitor begins to charge. After the switch has been in position 2 for 85.0 ms, the switch is moved back to position 1 so that the capacitor begins to discharge.

(a) Compute the charge on the capacitor just before the switch is thrown from position 2 back to position 1.

(b) Compute the voltage drops across the resistor and across the capacitor at the instant described in part (a).

(c) Compute the voltage drops across the resistor and across the capacitor just after the switch is thrown from position 2 back to position 1.

(d) Compute the charge on the capacitor 85.0 ms after the switch is thrown from position 2 back to position 1.
