Question details
From your values of L and C obtained in part 2 under analysis, calculate the resonant frequency according to equation (16) of lab manual. Compare this to the measured value you obtain in part 4 under analysis.
Equation16:
V. Resonance. from equations (7) and (10) that For a fixed value of inductance and capacitance, it can be seen the capacitive reactance decreases with increasing while the inductive reactance increases with frequency it possible to obtain a increasing frequency. Thus, varying frequency, is resonance. The where Xc If this is met, the circuit is said to be at frequency, usually referred condition is given by: to as the frequency, at which this occurs 2 LC It should be noted that if the frequency of an AC circuit is made equal to the resonant frequency, the value of the impedance given by (14) attains its minimum. Also, while in resonance, equation the rms current in the circuit, using equation (15), is a maximum. Procedure: i. Measure the AC current using only a resistor. (A) Assemble the apparatus thematically shown in Figure 2 with only the resistor R in the sc circuit. The AC power supply is a low frequency oscillator. The frequency and the voltage are set uency to 5000 Hz. Read the current as you vary the independently at desired values. Set the freq voltage between 1.0 and 6.0 V.Record your readings on the datasheet. between 1000 and 8,000 Hz. Record your readings on the datasheet. NOTE change the frequency, you may have to adjust the voltage to 5.0 V. The oscillato As you uency. Make sure you maintain a 5.0 output voltage may change a little bit as you vary the freq V value for each frequency set in 2. Measure the AC current using only a capacitor. Assemble the apparatus schematically shown in Figure 3 with only the capacitor C in the circuit. Set the frequency to 5000 Hz. Read the current as you vary the voltage between 1.0 and 6.0 V Record your readings on your datasheet. 3. Measure the AC current using only an inductor. Assemble the apparatus schematically shown in Figure 4 with only the inductor L in the circuit. Set the frequency to 5000 Hz. Read the current as you vary the voltage between 1.0 and 6.0 V Record your readings on your datasheet. NOTE The resistance of the inductor, due to its physical composition, is in the range of a few hundred ohms. This value is much smaller than the value of the inductive reactance at 5000 Hz. Thus, it is neglected in this experiment. The error for this omission is in the order of one percent. 4. Measure the AC current using the three elements in series. Assemble the apparatus schematically shown in Figure 5. Set the frequency to 5000 Hz. Read the current as you vary the voltage between 1.0 and 6.0 v. Record your readings on your datasheet. 5. Measure the AC current in resonance. Use the apparatus as assembled in part 4 above. Set the power supply to of V, you vary the frequency. Look for a maximum in the current. Once part 1 (B). Read the current as
