The Capacitor Charging Graph is the a graph that shows how many time constants a voltage must be applied to a capacitor before the capacitor reaches a given percentage of the applied voltage. A capacitor charging graph really shows to what voltage a capacitor will charge to after a given amount of time has elapsed.
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).
C affects the charging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to charge up, which leads to a lesser voltage, V C, as in the same time period for a lesser capacitance. These are all the variables explained, which appear in the capacitor charge equation.
When a capacitor charges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear.
Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then
The time it takes for a capacitor to charge to 63% of the voltage that is charging it is equal to one time constant. After 2 time constants, the capacitor charges to 86.3% of the supply voltage. After 3 time constants, the capacitor charges to 94.93% of the supply voltage. After 4 time constants, a capacitor charges to 98.12% of the supply voltage.
