-Turn the TRIG LEVEL until you see a stationary picture of two sinewaves on the oscilloscope screen. Record the VOLTS/DIV settings of CH1 and CH2 and all your wire connections in the incomplete sketch shown on Part III of the worksheet; again show which case corresponds to actual windings of your small and large coils. Draw the observed voltage signals in the grid provided on your worksheet. Make sure you note which voltage signal is the induced one, $V_2$, from the large coil and which voltage signal $N_1$, is from the AC generator or across the small coil (you can switch the signals off simply by setting the input of that channel to GND temporarily). Label the signals on your graph and indicate the voltage and times scales of the boxes. Measure the peak-to-peak amplitude (from the minimum to the maximum) of your voltage signals with the oscilloscope (see Lab # 2) and record their values on the graph on your worksheet.+Turn the TRIG LEVEL until you see a stationary picture of two sinewaves on the oscilloscope screen.

 BE CAREFUL! When observing the signals from Channel 1 and Channel 2 remember that the signal for each channel has its own VOLT/DIV setting. Take this into account when labeling your sketch and when computing the amplitude of each wave.  (Their TIME/DIV settings are the same.)  ​ BE CAREFUL!
