Experiment 5: RC Circuits Abstract The purpose of this lab is to learn and understand RC Circuits. An RC circuit is composed of at least one resistor and at least one capacitor. A capacitor is composed of two plates with either air or an insulator also known as a dielectric between the plates. We do not want the plates to be touching‚ because then we would only have a conductor. The insulator between the plates is also known as the dialectic‚ which affect how the capacitor will store

PHY 156 4870 Lab Report #6: RC Circuits October 14th‚ 2011 Objectives: The purpose of this lab is to observe the charge and discharge curves of a capacitor and determine its time constant. The capacitor is observed with respect to the voltage traveling through the capacitor.

RC Circuits •In this presentation‚ circuits with multiple batteries‚ resistors and capacitors will be reduced to an equivalent system with a single battery‚ a single resistor‚ and a single capacitor. Kirchoff ’s laws will be stated‚ and used to find the currents in a circuit. In addition‚ the equation for the time-constant of an RC circuit will be derived. Ohm ’s Law When a battery is connected to a resistor‚ the battery will cause a current to flow through the resistor. The larger the voltage

Experiment 13 Charging and Discharging Capacitors 1. Introduction In this experiment you will measure the rates at which capacitors in series with resistors can be charged and discharged. The time constant RC will be found. Charging a capacitor. Consider the series circuit shown in Fig. 1. Let us assume that the capacitor is initially uncharged. When the switch S is open there is of course no current. If the switch is closed at t=0‚ charges begin to flow and an ammeter will be able to

Ohm’s Law is V = I * R or in some cases I = V / R. The next two laws were established by a German physicist by the name of Gustav Kirchhoff. Kirchhoff’s first law is his voltage law. Kirchhoff’s Voltage Law (KVL) states that around any loop in a circuit‚ the voltage rises must equal the voltage drops. The next law that Kirchhoff introduced was his current law. Kirchhoff’s Current Law (KCL) states that the total current entering a junction must equal the total current leaving the junction. These laws

As well as the introduction to the voltage division. The Ohm’s Law states that the current through a conductor between two points is directly proportional to the potential difference across the two points (V = IR). The Kirchhoff’s Voltage Law states that the directed sum of the electrical voltage

Alternating Current RC and LRC Circuits Lab 7 November 12‚ 1012 109989- 5:30 PM Abstract Within this experiment we recorded that the theoretical capacitance of 0.470 is accurate with the capacitor from box C. The LRC circuit is proven to have a voltage accurate with the measured generator voltage because the largest percentage of error ‚ 0.55 % error‚ is much lower than 5% error. Summary The idea of the alternating current RC and LRC circuits lab is to record the value
