In no less than 250 words, explain clearly how a capacitor gets charged when a battery is applied to the capacitor?

Expert Solution

Below are the points which will clear the charging of a Capacitor by Battery.

C=Q/V in Farads

1) A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply.

2) Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting. So, if a capacitor is connected to a 9-volt battery, it will charge up to 9 volts. If a capacitor is connected to a DC power supply outputting 15 volts, it will charge up to 15 volts. All that has to be done is for the positive side of the DC voltage source to be connected to the positive side of the capacitor, the longer lead, and the negative side of the DC voltage source be connected to the negative side of the capacitor, the shorter lead.

3) In this case, the capacitor charges up to 9 volts, since it's connected to a 9-volt battery. Many of the times while charging a capacitor, a resistor is used in series with the capacitor and voltage source to decrease the amount of current that flows through the capacitor, so that the capacitor isn't damaged. This is usually recommended.

An 8.5 nF capacitor is charged up by a 20 V battery. The battery is removed and replaced with a coil of wire. It then takes 7.3 x 10-5 s for this now LC circuit to undergo a full charging cycle. (a) Calculate the inductance of the coil (b) Calculate the total energy of the circuit (c) Calculate the charge on the capacitor after 1 x 10-5 s.

A 8.0 µF capacitor is charged by a 11.0 V battery through a resistance R. The capacitor reaches a potential difference of 4.00 V at a time 3.00 s after charging begins. Find R in kO. I've been using , but I'm not sure if that is right since I just CAN'T get the right answer...I keep getting 370.7 kO (incorrect).
