8. An RC circuit has a 12 volt battery, 6 MQ resistor, 3 uf capacitor, and a switch.
The switch is open and the capacitor is uncharged at t<0. The switch is closed
at t = 0, and the capacitor begins to charge. Calculate...
a) the time constant
=18 Seconcs
b) the voltage across the capacitor at t = 6s
V=
V= 5.67 X167
c) the voltage across the resistor at t = 6 s
V=5.67X10
d) the charge on the capacitor, at t = 6 s
123:3.5 E-7
%3D
e) the time required for the voltage across the capacitor to be 90% of the voltage
coming from the battery.
•%6 = (1-e/0)
-t/16
96 -1 = -e
-In(4-1) = t/16
- 18 ln (1+) = E
t= 41.4
