R-C Circuits

Introduction: The objective of this experiment was to understand the concepts behind RC (Resistor-Capacitor) sets. A circuit that has a granting immunity and a condenser in series is called an R-C circuit. A typical R-C circuit consists of a bombardment that has an electric potential ( ), a project to the battery and the immunity and electrical capacity in series. When the switch is open the condenser is uncharged and the electromotive force deflexion crosswise it is zero. The possible difference across the resistivity is cost to the emf of the battery. As curtly as the switch is closed (t = 0), up-to-date flows from the battery and charges the capacitor. When the current flows through the electric resistance, the electromotive force difference across it decreases everyplace term date the electromotive force difference across the capacitor increases. later a spacious quantify, the capacitor becomes all-encompassin gy charged and the current cabbage flowing. The electromotive force difference across the resistor goes to zero while the potential difference across the capacitor becomes maximum and is equal to the emf of the battery. The rate of decrease in the potential across the resistor is determined by the product RC, known as the time constant of the circuit.

The voltage shave across the resistor in case of charging RC circuit is given by R = V_0 e^(-t/RC) The voltage across the capacitor increases exponentially over time and is given by C = V_0 ?(1-e?^(-t/RC) ) Now after the capacitor is fully charged the battery is removed from the circuit an d the capacitor is discharged. In this case ! both the voltage drop across the resistor and capacitor decreases. The voltage drop across the resistor in case of discharging RC circuit is given by R = ?-V?_0 e^(-t/RC) The voltage drop across the capacitor in case of discharging RC circuit is given by C = ?-V?_0 e^(-t/RC) A typical R-C circuitIf you want to get a full essay, order it on our website: BestEssayCheap.com
