It can be found indirectly by measuring the time required for the voltage to fall to V. For this reason it is called the time constant, which we call t (tau). When the same capacitor discharges through the same resistor, Vſt) - V.e- The product of the resistance and capacitance, RC, governs the time scale with which the changes take place. Use Multisim to simulate the RC filter behavior Background and Theory Resistance-Capacitance Circuits Theory (see textbook) shows that for a capacitor, C, charging through a resistor, R, the voltage across the capacitor, V, varies with time according to: Vit) - V.

The current through the resistor must be equal in magnitude (but opposite in sign) to the time derivative of the accumulated charge on the capacitor.In this part of the experiment, you will make measurements to The voltage across the capacitor, which is time-dependent, can be found by using Kirchhoff's current law. Once the circuit is closed, the capacitor begins to discharge its stored energy through the resistor. The simplest RC circuit consists of a resistor and a charged capacitor connected to one another in a single loop, without an external voltage source. This article considers the RC circuit, in both series and parallel forms, as shown in the diagrams below. In particular, they are able to act as passive filters.
These circuits, among them, exhibit a large number of important types of behaviour that are fundamental to much of analog electronics.
These may be combined in the RC circuit, the RL circuit, the LC circuit, and the RLC circuit, with the acronyms indicating which components are used. There are three basic, linear passive lumped analog circuit components: the resistor (R), the capacitor (C), and the inductor (L).
