A component that opposes the flow of electric current, dissipating energy as heat.

A component that stores electrical energy in an electric field.

The total capacitance of a circuit when multiple capacitors are combined, behaving as a single capacitor.

A measure of how quickly a capacitor charges or discharges, calculated as $\tau = R_{eq}C_{eq}$.

A circuit containing both resistors and capacitors, used for timing and filtering applications.

Initially, the capacitor acts like a wire, allowing charge flow. As it charges, its potential difference increases, current decreases, and energy is stored until fully charged with zero current.

The capacitor releases stored charge through the resistor. Potential difference, current, and stored energy decrease over time until reaching steady state.

Sum the inverses of individual capacitances: $\frac{1}{C_{eq,s}} = \sum_{i} \frac{1}{C_i}$.

Simply add the individual capacitances: $C_{eq,p} = \sum_{i} C_i$.

Multiply the equivalent resistance and equivalent capacitance: $\tau = R_{eq}C_{eq}$.

It increases the time constant, slowing down the charging/discharging process.

It increases the time constant, slowing down the charging/discharging process.

The current decreases over time, approaching zero when the capacitor is fully charged.

The stored energy in the capacitor is dissipated as heat in the resistor, and the capacitor's voltage decreases.

Charge begins to flow, accumulating on the capacitor plates, and a current flows through the resistor.
