PHY124 AC CIRCUITS Exp. 6 Abstract In this experiment we will deal with circuits driven by an AC (sinusoidal) power source. AC quantities (AC voltages, AC currents, AC impedances) are more complicated than their DC counterparts (DC voltages, DC currents, DC resistances). The complication is that every such quantity has a specifc magnitude (expressed either as RMS or peak) and a specifc phase. 1 Knowledge, Understanding, and Skills You should have a “hands-on” experience and ability with all the following: How to use an oscilloscope to plot two waveforms. How to set your function generator to make a waveform of any desired character. How to use an oscilloscope to measure both the magnitude and the phase of an AC waveform. How to calculate total impedances, phases, and voltages within an AC circuit. The meaning of “High Pass Filter”, “Low Pass Filter” and “Resonant Circuit”. The formulas for time constant in a circuit. 2 AC Filter Circuits and Transient Response Filter circuits are either RL or RC circuits. The procedure to measure and analyze both such circuits are described below. However, for the sake of time, some lab groups will measure only RL circuits and other lab groups will measure only RC circuits. All lab groups are responsible for understanding both types of circuits. Figure 1 shows all the equipment reauires for the lab. Figure 2 is a close-up view of the component board from which you will be wiring your circuits. 2.1 Limitations of your Oscilloscope and Waveform Generator During this laboratory experiment, you will be using two devices that plug into wall power: the oscilloscope and the function generator. Each of these devices uses a BNC-to-Banana convertor as indicated in Figure 3.
