Part I. A. Set the function generator to high-Z, 1 kHz, and 100 mVrms, and place its output across the secondary leads, 4 and 5, of the transformer. Use the DMM, which reads rms voltage when set to "AC V", to adjust V45. 1. The voltage across the primary leads, 1 and 3, is 2. The voltage across Leads 2 and 3 is Calculate V13 V45 =n= V23 n V45 2 B. Place a 5 Vrms, 1 kHz sine wave across the primary leads, 1 and 3; again, use the DMM to adjust the voltage. The voltage across the secondary leads, 4 and 5, is V45 = C. Repeat Part I.B, but put the input across Leads 2 and 3, instead of 1 and 3. Make sure that the input voltage is still 5 Vrms. V45 = Calculate: V13 V45 =n= V23 V45 Compare these values with the results of Part I.A. = SIN V13 = V23= n ||
Part II. Construct the following circuit. Again, use the multimeter when setting VR₁; be sure to measure the correct VR1. n:1 VR1 ww R₁ = 10 KQ Note that since VR1 = R₁i₁ and v45 = -R₂12, Eq. (2) gives n=- = V45 R1 VR1 R₂ V2 Adjust the function generator so that VR1(t) is 1 Vrms, 1 kHz. ₂(t) is Calculate n and compare with the results of Part I. 4 5 R₂ = 50 0 V45
Part III. Construct the following circuit. The only changes from the circuit in Part II are the location of the 10 k resistor and where the voltages are measured. You will need an oscilloscope to measure the phase. R, = 10 ΚΩ ww + Vs + V13 20 1 n:1 R13 Note that V₁3(t) = nV54= n(−R₂i2) = R₂n²i₁ = R₁3i₁, so that, ideally, R₁3 = n²R₂ is the effective resistance between Leads 1 and 3. 4 A. Using the DMM, adjust the function generator so that Vs is 1 Vrms. 1. V13(t) is 2. Are vs(t) and v₁3(t) in phase? Should they be in phase if the transformer is ideal? 3. Use voltage division to show that R₂ = 50 Q R₁V13 Vs - V13 V13 = If not, what is the phase difference? (D1) R13 4. Calculate R₁3. 5. From R₁3 = n²R2, calculate n and compare with the results of Parts I and II. n =
B. Repeat Part III.A, but with the 10 k resistor connected to transformer Lead 2, instead of Lead 1. Readjust the amplitude of the function generator so that vs 1 Vrms, if = necessary. 1. 2. phase difference: 3. V23= 4. R23 SIN n = ||
