\( \tau = R C \) is called the time constant of the circuit.Įnter the source voltage \( V_0 \), the resistance \( R \), the capacitance \( C \) as positive real numbers with the given units then press "Calculate". The voltage \( v_R(t) \) across the resistor is given by The voltage \( v_C(t) \) across the capacitor is given by
When a voltage step function of the form \( v_i(t) = V_0 u(t) \) is the input voltage in the given cicuit, we have : Inputs Select Input Type Frequency Output Capacitance (pF) Reactance () Admittance (S) Overview This calculator is designed to compute for a capacitors reactance and admittance given the capacitance value and the frequency. The formulas developed in RC circuit response to a step voltage are presented here as they are used in the calculator. A calculator for solving the capacitance, reactance, and admittance of a capacitor.
