... step, measure the V2 2) Fill in the below table V1 (Volt) A1 (Ampere) V2 (Volt) V1/V2 0 0.000 0.000 0.000 10 0.014 1.153 8.673 20 0.022 2.305 8.677 30 0.022 3.529 8.501 40 0.033 4.73 8.457 50 0.036 5.91 8.460 60 0.040 7.14 8.403 3) Explain why the ratio V1/V2 is not a constant value. It is because the core loss of the sum of the hysteresis loss and eddy-current of the magnetic. Alter the path of Magnetic flux: Procedure 1) Based on the above, modify the structure of your transformer. Between the yoke and the U-core, insert some paper provided between them only on one end. 2) Fix the output voltage from the adjustable transformer to 50V 3) Record the V2 with different no. of piece of paper inserted. No. of piece of paper inserted V2 (Volt) 0 5.96 1 5.79 2 5.66 3 5.53 4 5.45 5 5.53 4) Explain why there is some noise on your designed transformer when paper is inserted? When the No. of paper increase the voltage will decrease, it is because papers block the flux flowing through the magnetic so the voltage decrease. Efficiency and Voltage regulation: Procedure 1) Connect the below circuit. 2) Keep the output voltage on adjustable transformer ...
