- (Extension question) Voltage can be measured using an oscilloscope by multiplying the "volts per division" setting by the number of divisions (or boxes) between the signal and the centre "zero" line on the oscilloscope grid. For an a.c. signal, the "peak voltage" is the maximum voltage reached in any cycle. For each of the following signals, determine the d.c. voltage or the a.c. peak voltage shown. The "volts per division" setting is given in each case.
