Question

A dc voltage with ripple is given by v(t)=[100+10sin(ωt)5sin(3ωt)]v(t) = [100 + 10 \sin(\omega t) - 5 \sin(3\omega t)] volts. Measurements of this voltage v(t)v(t), made by moving-coil and moving-iron voltmeters, show readings of V1V_1 and V2V_2 respectively. The value of V2V1V_2 - V_1, in volts, is _________.
