An a. c. source is connected to an oscilloscope. The waveform of the alternating potential
difference from the source is displayed on the oscilloscope screen as below.
a) The Y-gain setting of the oscilloscope is 2.0 V/cm. Determine the amplitude of the
alternating potential difference.
c) The time-base setting of the oscilloscope is 0.010 seconds per cm.
Determine the frequency of the alternating potential difference.
