Question

The AC V-meter in the figure is designed to measure the RMS value
of the input sinusoidal voltage u(t). The diodes are assumed to be
ideal; M is a moving-coil type measuring unit with Ri=2k (internal
resistance) and im=100A (current for full-scale deflection).
a) Draw the current through M in scale and calculate R1 for a
nominal voltage of 100V.
b) The class of the measuring unit is given as 0.5. Calculate the
maximum acceptable tolerance for the resistors (all of the
same tolerance), if the V-m is required to be of the class 1.5 max.
