Discussion of Principles A capacitor consists of two conductors separated by a small distance. You will study this circuit and ways to change its effective capacitance by combining capacitors in series and parallel arrangements. This experiment features an RC circuit, which is one of the simplest circuits that uses a capacitor. It is even possible to charge several capacitors to a certain voltage and then discharge them in such a way as to get more voltage (but not more energy) out of the system than was put in. A capacitor can be slowly charged to the necessary voltage and then discharged quickly to provide the energy needed. In plasma physics short pulses of energy at extremely high voltages and currents are frequently needed.
Plasma physics makes use of the energy storing ability of capacitors. Capacitors pass AC current, but not DC current, so they are used to block the DC component of a signal so that the AC component can be measured. Capacitors have several uses, such as filters in DC power supplies and as energy storage banks for pulsed lasers. It is a powerful all-in-one instrument consisting of all the essential instruments found in a lab such as power supply, scope, function generator, and digital logic analyzer.Lab 4 - Charge and Discharge of a Capacitor Introduction Capacitors are devices that can store electric charge and energy. Analog Discovery Studio was designed for students for learning electronics. We will also use it to generate an AC signal and view the AC frequency response. You can use your desktop computer or any mobile device to build and simulate the circuit.Īlong with Multisim Live, we will use the Analog Discovery Studio to measure the charging and discharging time of the RC circuit. Multisim Live is a web-based SPICE circuit simulation, schematic capture that works directly from web browsers, no software installation is required.
You will also investigate the AC response of the RC circuit and learn how to design a low-pass and high-pass filter.įor this lab, you will use Multisim Live to confirm the theory before proceeding to prototype the circuit on the Breadboard Canvas. In this lab, you will investigate how the RC circuit responds when a DC voltage source is applied to it and learn about the charging and discharging properties of the capacitor.
