Resistors are often used in combination with capacitors in order to control the charge and discharge time necessary for the intended application. Resistance directly affects the time required to charge a capacitor. As resistance increases, it takes more time to charge a capacitor. What is the function of a capacitor?
As the capacitor charges the voltage across the resistor drops ( V_R = V - V_"cap") so the current through it drops. This results in a charge curve that starts off at it's maximum charge rate and tails off to a slower and slower charge rate as the capacitor nears its fully charged state.
While capacitors store and release energy, resistors control the flow of current. This dichotomy allows engineers to create intricate circuit behaviors, such as time delays, filtering, and frequency-dependent responses. Capacitors exhibit characteristics like capacitance, voltage rating, and ESR (Equivalent Series Resistance).
The same thing happens when discharging through a resistor, with maximum discharge at the beginning. The time taken for a particular capacitor value to charge to 63.2% of full charge through a particular resistor value to is known as the "time constant" for the RC combination.
Since the capacitor is basically a charge storage, there is no such equation as this hence you can say there is no electrical resistance. But if you define resistance by its truest meaning, the capacitor is resistant to low frequencies but allows high frequency currents to pass through. Why resistor is used in parallel with capacitor?
The larger the resistor , the slower the charge/discharge rate. The larger the capacitor , the slower the charge/discharge rate. If a voltage is applied to a capacitor through a series resistor, the charging current will be highest when the cap has 0 Volts across it. (i.e. when it is first connected the full voltage will be across the resistor).
Capacitors and resistors both control electrical current, but they have different applications. Resistors are used to reduce or limit the flow of current, while capacitors are used to store energy. As a result, resistors …
