Question

The values of the components in a simple series RC circuit containing a switch and an initially uncharged capacitor (see figure below) are C = 1.50

The values of the components in a simple series RC circuit containing a switch and an initially uncharged capacitor (see figure below) are C = 1.50 mu F, R = 2.80 M?, and epsilon = 10.0 V. the charge on the capacitor...a long time after the switch is closed the current in the resistor immediately after the switch is closed The rate at which energy, 1.7 s after the switch is closed, is being dissipated in the resistor Your response is within 10% of the correct value. This may be due to round off error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize round off error. mu W

Explanation / Answer

V(t)=v(1-e^-t/Rc)

Pcapacitor=[V^2/R] .(e^-t/Rc - e^-2t/Rc)

here v=10s

t=1.7 s

R=2.8*10^6 ohm

C=1.5*10^-6 F

RC=4.2

t/RC=0.404

e^-t/Rc=0.667

e^-2t/Rc=0.445

V^2/R=3.57*10^-5

P cap=3.57*10^-5.[0.667135-0.445]

Pcapacitor=7.9*10^-6 W
