If a 0.1 µF capacitor and a 2.2 k▲ resistor are connected in series across 30 VDC, how much voltage will the capacitor drop after charging for just one time constant?

If an uncharged capacitor, a resistor, a switch and a 12 V battery are connected in series, what is the voltage across the capacitor at the instant the switch is closed?

If an uncharged capacitor, a resistor, a switch and a 12 V battery are connected in series, what is the voltage across the capacitor after it is fully charged?

If an uncharged capacitor, a resistor, a switch and a 12 V battery are connected in series, at approximately what time will the capacitor reach full charge?

If a 0.047 µF, 0.047 µF and 0.47 µF capacitor are connected in series across a 25 V source, the total capacitance equals _ and each 0.047 µF capacitor drops .

There is often a capacitor connected to ground between the bridge rectifier and the voltage regulator in a power supply. In order to limit surge current a bridge and the regulator.
Is inserted between the

In a transistor amplifier the input ac signal and the output of the amplifier must be connected in a way that not does affect the dc bias voltage. This is accomplished by using a(n)capacitor.

Upon checking the voltage output of a power supply with an oscilloscope, you notice an unusually large amount of ripple. What could possibly be the problem?
