A 8.0-μF uncharged capacitor is connected in series with a 6.0-kΩ resistor,an ideal 20-V dc source,and an open switch.If the switch is closed at time t = 0.0 s,what is the charge on the capacitor at t = 9.0 ms?
B)37% of the minimum charge
C)17% of the maximum charge
D)68% of the minimum charge
E)96% of the maximum charge
A 2.0-μF capacitor that is initially uncharged is charged through a 50-kΩ resistor.How long does it take for the capacitor to reach 90% of its full charge?
A fully charged 37-µF capacitor is discharged through a 1.0-kΩ resistor.If the voltage across the capacitor is reduced to 7.6 volts after just 20 ms,what was the original potential across the capacitor?
A 2.0-μF capacitor is charged to 12 V and then discharged through a 4.0-MΩ resistor.How long will it take for the voltage across the capacitor to drop to 3.0 V?
