Peak, peak to peak, and r.m.s. values
A cathode ray oscilloscope (CRO) is used to view a voltage
waveform, and to measure the peak voltage (K
p
) (Figure 6.4),
which is the amplitude. Note that the peak to peak voltage
Vp/p = 2V
p
(K
p
is the maximum value). A.c. voltmeters, both
analogue and digital, will read the r.m.s. (root mean squared)
value. The r.m.s. value of the voltage is equal to the value of a d.c ...
