Customer ServiceVC - V C is the voltage that is across the capacitor after a certain time period has elapsed. VIN - V IN is the input voltage which is connected to the capacitor which supplies it with voltage, so that the capacitor can charge up. Without V IN, a power source, a capacitor cannot charge.
Customer ServiceData given: R = 40Ω, C = 350uF, t is the time at which the capacitor voltage becomes 45% of its final value, that is 0.45V Then it takes 8.37 milli-seconds for the voltage across the capacitor to reach 45% of its 5T steady state condition when the time constant, tau is 14 ms and 5T is 70 ms.

Customer ServiceSecond what makes a capacitor "bigger" (in the sense of more capacity). If you take an electron away from a positive charge, it develops a voltage. The more the charges are separated, the higher the voltage is. So the voltage per charge of a capacitor goes up as the plates get more separate*, and the capacitance goes down.

Customer ServiceWhen an increasing DC voltage is applied to a discharged Capacitor, the capacitor draws what is called a "charging current" and "charges up". When this voltage is reduced, the capacitor begins to discharge in the opposite direction.
Customer ServiceAs a result the current in the circuit gets gradually decreased. When the voltage across the capacitor becomes equal and opposite of the voltage of the battery, the current becomes zero. The voltage gradually increases across the capacitor during charging.
When a capacitor loses its charge, the voltage across the capacitor will start to decrease. For a constant resistor, the current will also start to reduce as the voltage decreases. Eventually, the voltage across the capacitor will hit the zero point at a 5-time constant ($5\tau $). Similarly, the current will also go to zero after the same time duration.
Initial Current: When first connected, the current is determined by the source voltage and the resistor (V/R). Voltage Increase: As the capacitor charges, its voltage increases and the current decreases. Kirchhoff’s Voltage Law: This law helps analyze the voltage changes in the circuit during capacitor charging.
Capacitor Charging Definition: Charging a capacitor means connecting it to a voltage source, causing its voltage to rise until it matches the source voltage. Initial Current: When first connected, the current is determined by the source voltage and the resistor (V/R).
A rule of thumb is to charge a capacitor to a voltage below its voltage rating. If you feed voltage to a capacitor which is below the capacitor's voltage rating, it will charge up to that voltage, safely, without any problem. If you feed voltage greater than the capacitor's voltage rating, then this is a dangerous thing.
This is because resistance represents an impedement. It slows down and lessens current, so that charging is slower, and, thus, the resultant voltage across the capacitor will be less than with a lesser resistance. Capacitance, C - C is the capacitance of the capacitor in use.
