Question

Given the circuit below: (Please review transformer turns ratio) Vpeak =5Vpki VDC = 12 de You measure in the lab the output voltage across resistor R1. T1 vum VAC 5Vpk 1kHz 09 R1 1k0 1:5 VDC 12V Given the Figures A-D below, choose the best Figure that best describes the transformer output voltage waveform you would expect to see across resistor, R1 FIG A 5V OV -5V FIG B 17 7V OV

Answer 1

Given w VAC Sypk 1k2 1:5 Hp 1643 o 1 / NS = Voc -127 Vi = n + -5 Vp= 5 Vpk + 12V DLL 17 ke have, Vp= 7 pe Vp Vs 11 Hp NS C) for V;= 7y lie vp=7 7 VS = Vs: 357 Lower voltage () for Vi= 177 ie Vp=171 1 17 VS Vs=850 upper voltage ... The olp ware form is 85 Fing is the comect Answer. 35V CScanned with Canlscanner
