Lab 10 Low Pass and High Pass Filters Objective To study the behavior of RC and RL circuits when they are connected to AC power supply. Material Function generator‚ resistor‚ capacitor‚ inductor‚ wires‚ breadboard‚ oscilloscope Procedure RC Low Pass Filter We use a 10KΩ resistor and a 0.01μF capacitor in a series and prepare a function generator and a oscilloscope. Next‚ we measure the each voltage by changing the frequency (Start from 10‚ 20‚30‚50‚70Hz). The measurement repeats

For any node of the circuit in I = out I . Note that the choice of “in” or “out” for any circuit segment is arbitrary‚ but it must remain consistent. So for the example of Fig. 2 we have I1 = I2 + I3 . 2. For any closed circuit‚ the sum of the circuit EMFs (e.g. batteries‚ generators) is equal to the sum of the circuit voltage drops:

Vuchic Background‚ Philosophy‚ and Motivation: Over the past few decades‚ the scope of electrical engineering (ESE in the context of our department) has expanded to a degree where the discipline risks effacement by diffusion [1]. This calls for hard thinking on how to reform traditional course offerings in our discipline in order to avoid incoherent

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

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

Superposition theorem is a way to determine currents and voltages in a linear circuit that has multiple sources by taking one source at a time. the current in any given branch of a multiple-source linear circuit can be found by determining the currents in that particular branch produced by each source acting alone‚ with all other sources

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
