# RC circuit (Voltage of the capacitor at Series circuit

## Description

A resistorâ€“capacitor circuit (RC circuit), or RC filter, is an electric circuit composed of resistors and capacitors driven by a voltage or current source. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit.

The simplest RC circuit is a capacitor and a resistor in series. Viewing the circuit as a voltage divider, the voltage across the capacitor is related to the input voltage, the capacitance of the capacitor and the resistance of the resistor.

## Variables

V_{C} | Voltage across the capacitor (V) |

R | Resistance of the resistor in series (ohm) |

C | Capacitance of the capacitor in series (F) |

s | Complex frequency (ohm^{-1}*F^{-1}) |

V_{in} | Input Voltage (V) |
