This RLC circuit allows the capacitance to be varied. Frequency is 450 Hz, and resistance is set to 500 ohms. Prevent floating ground by grounding C. ASU copyright This RLC circuit allows the inductance to be varied by inserting an iron core. Capacitance is .01 mf, frequency 450 Hz, and R is 80 ohms. The LCR are in series and the oscilloscope is parallel across the capacitor. Capacitor is hooked to ground. ASU copyright Set frequency to 2300 Hz resistance to 300 ohm. The inductance has a range of 6 mH when the iron core is out to 38 mH when it is inserted. The Capacitance has a range of 140 to 640 pF. This is maximum range for C and minimum range for L. The resistance is 10 ohms. ASU copyright Capacitance is maximum range and inductance is maximum range as well. The resistance is 10 ohms. ASU copyright Capacitance is minimum range and inductance is minimum range as well. ASU copyright Capacitance is maximum range and inductance is at a minimuml range. The resistance was raised to 30 kilo ohms. ASU copyright Capacitance is minimum range and inductance is a maximum range. ASU copyright

| Copyright © 2000 | Instructions: The L,C,R and signal generator are set in series. Channel two is set in parallel with the capacitor. Set the function generator to square wave and 2300Hz. Set resistance to 100 ohms. To switch from the variable C to the variable L disconnect the 2 BNC to RCA splitters from channel 1 and 2 on the oscilloscope and then connect the other 2 BNC to RCA splitters from the other circuit. The oscilloscope sometimes has a floating ground problem. This can be avoided by placing the component being measured, capacitor in this case, to the ground of the source, function generator here. |
