Answer:
peak voltage is the maximum value = 10V.
Average voltage= 0V since signal is hovering always somewhere around 0V only.
time period = 5milli second= 0.005 seconds since signal is repeated after every 5ms.
frequency= 2x pi/ time = 6.28/0.005= 1256 Hertz= 1.256 KHz.
RMS= peak/sqroot(2) = 10/1.414 = 10×1.414/(1.414×1.414) = 10×1.414/2= 5×1.414= 7.07 V.
