Web1 Introduction to RL and RC Circuits Objective In this exercise, the DC steady state response of simple RL and RC circuits is examined. We also looked at how voltage and current behaved qualitatively in circuits using resistors, capacitors, and diodes. Explore the effect of space and dielectric materials inserted between the conductors of the capacitor in a circuit. Draw a purely capacitive AC circuit diagram connected to oscilloscope. The coupling capacitance C 1 lets only the alternative current (AC) signal pass as an input of the CEA configuration while blocking the direct current (DC) to go from the supply to the source. . %%EOF
(1 - e^{(\frac{-t}{\tau})})$$. Then, the AC voltage supply was turned on initially at 2V then adjusted to 4V, 6V, 8V and 10V. WebThe lab reports are due on the next lab meeting.

Normally the current (which must be equal at all points along a series circuit) is used as a reference signal in AC circuits. An alternating source of emf is connected across a capacitor of capacitance C (Figure: a). Using the other meter, record the frequency f, and the RMS AC voltages across the signal generator V. s, the resistor V. R, and the capacitor V. C. 4. Experimentally determine the impedance Z of a series RLC circuit and compare to the calculated value (lab report) Materials & Resources 1. Capacitors do not behave the same as resistors. WebExperiment 1: RC Circuits Introduction In this laboratory you will examine a simple circuit consisting of only one capacitor and one resistor. In this experiment, a capacitor was charged to its full capacitance then discharged through a resistor. Measure both the input and the output using the oscilloscope. The general term for the sum of all the resistance and reactance WebDISCUSSION Intro In this experiment, the capacitor was connected to the oscilloscope and AC power supply. WebMake actual measurements of all resistor and capacitor values that you use in the following circuits and use them in your post-lab to report relative errors between the ideal circuit output and the actual circuit. represents the final charge on the capacitor that accumulates after an infinite length of time, R is the circuit resistance, and C is the capacitance of the capacitor. Alternating current in a simple capacitive circuit is equal to the voltage (in volts) divided by the capacitive reactance (in ohms), just as either alternating or direct current in a simple resistive circuit is equal to the voltage (in volts) divided by the resistance (in ohms).
