rc circuits lab report

This laboratory experiment is designed to investigate the behavior of capacitor responses of RC circuits, the basis for most electronic timing circuits. This is commonly known as an RC circuit and is used often in electronic timing circuits. Lab Report Template. Experiment 7: RC Circuits Introduction Capacitors are used in timing circuits in many devices. The time that your dome lights inside your car stay on after you turn o your cars ignition at night is one example of how a capacitor can be used to. Nov 13,  · This lab experiment focuses on RC circuits, which are made up of resistors (R) and capacitors (C). Resistors can affect how hard it is to push charge through the wire while capacitors are devices made up of two plates that can be charged or discharged. It can generate and store electricity from the potential difference built across them.

Capacitors in series. Capacitors in parallel. Figure 1. Figure 2. Figure 3. Schematic of an RC circuit. The components in the rc circuits lab report box are analogous to a square-wave generator with outputs at points and. The switch continuously moves between points and creating a square wave as shown in Figure 4a. Figure 4. A voltage pattern known as a square wave.

Moving the switch in Figure 3 alternatively between positions and can produce this voltage pattern. When the switch is in positionthe input voltage is the peak voltage is. When the switch is moves to positionthe input voltage drops to zero, rc circuits lab report. A function generator more commonly produces square-wave voltages.

Figure 5. The RC circuit diagram. The oscilloscope's Channel 1 monitors the function generator while Channel 2 monitors the voltage drop across the capacitor, rc circuits lab report. Figure 6a. The square wave that drives the RC circuit.

When the switch in Figure 3 is in positionthe input voltage is the peak voltage is. In this experiment, this input voltage is read by the oscilloscope's CH 1. Figure 6b. The voltage drop across the capacitor of Figure 3 as read by the oscilloscope's CH 2.

The capacitor alternately charges toward and discharges toward zero according to the input voltage shown in Figure 6a. Here, the frequency and therefore period of the input square wave voltage is exactly such that the capacitor is allowed to fully charge and discharge.

The time constant,is equivalent torc circuits lab report, and is defined by Equations 11 or Charge as capacitor charges. Current as capacitor charges. Voltage across charging rc circuits lab report. Charge as capacitor discharges. Current as capacitor discharges. Voltage across discharging capacitor. Figure 7. A square wave with a longer period drives rc circuits lab report RC circuit and the voltage response across the capacitor is slightly different than that shown in Figure 6b.

It can be assumed that the circuits are the same for Figures 6 and 7. The capacitor charges in the same amount of time as the one shown in Figure 6b, but because the square-wave period is longer, the capacitor here remains charged until the input voltage drops once again to zero.

Figure 8. Capacitors of various capacitance values. Figure 9. The 10k W resistor. Figure Digital Multi-meter or DMM may be rc circuits lab report to measure resistance. The breadboard is used to connect circuit components. Notice the binding posts can be used to easily bring power from the function generator Figure You may find tutorials on using the breadboard in the On-line Assistance section.

Jumper wires for use with the breadboard Figure Use the pliers Figure 13 to insert these wires into the breadboard. Pliers should be used to insert resistors and jumper wires into the breadboard. The function generator is capable of producing sine, square and saw-tooth waves, rc circuits lab report. Oscilloscopes displays input voltages from two channels over time.

Here is a close-up of the Heath scope. Notice the location of all the switches, rc circuits lab report. All variable knobs should be off, that is, "pushed in or clicked off". Here is a close-up of the Goldstar scope. A sine wave output from a function generator as displayed by the oscilloscope.
