Ask Custom Question

Determine the current through the capacitor just before and just after the switch is closed in the figure. Assume steady-state conditions for t<0.

V1 = 12 V
C= 0.5uF
R1 = 0.68K Ohms
R2 = 1.8K Ohms

Solution Summary

The solution explains in detailed steps how to find the current through the capacitor described in the question, assuming steady-state conditions, for a range of values of t (time) with small portions of written explanation to accompany the calculations.

Solution Preview

a) Just before the switch is closed, i.e. at t = 0(-)

There is no current any where in the whole circuit. Voltage across the parallel combo. of C and R2 is zero and hence,

Current through C = 0.0 A

b) When the switch is closed at t= 0, the capacitor voltage cannot change ...
