PROCEDURE A (Frequency Response of a <strong>Series</strong> <strong>RLC</strong>Circuit)A1. Measure the actual resistance of the 470Ω resistor and the dc resistance of the 25mH choke and calculate the total series resistance [<strong>10</strong>-1].A2. Connect the Isolated Function Generator circuit shown in Figure 2-1 (pg. 17) to thecircuit of Figure <strong>10</strong>-1. Prepare to measure V CD PP , V R PP , V L PP and V C PP (individually).Figure <strong>10</strong>-1A3. MODE to CH-A(CH1).A4. Turn the Function Generator ON and set V CD to 6V PP , <strong>10</strong>00Hz.A5. Measure V R PP , V L PP and V C PP [<strong>10</strong>-2] using CH-A.A6. Calculate the current I, the inductive reactance X L , the capacitive reactance X C andthe phase angle θ [<strong>10</strong>-2]. Indicate if θ is leading or lagging.Note: Use R T when you calculate the phase angle θ.A7. Complete Table <strong>10</strong>-2 for each frequency shown.A8. Turn the Function Generator OFF, but do not change the circuit. It will be used inProcedure B.ELTK<strong>1200</strong> <strong>Experiment</strong> <strong>10</strong> Rev 5 113
