A PMMC instrument with FSD of 50 µA and Rm = 1700 N is used in the half wave rectifier voltmeter circuit shown in figure. The silicon diode (D1) must have a minimum (peak) forward current of 100 µA when the measured voltage is 20 % of FSD. The voltmeter is to indicate 50 Vrms at full scale. Calculate the values of R, and Rsh- R, \ISH IF Im Vm RSH D2 PMMC instrument

I am very lost on the steps it takes to complete these problems from start to finish, If at all possible can you please give a fairly detailed explanation of the steps you took to solve the problem. KCL, and KVL still confuse me and I'm unsure of how to get the equations on my own. I'm attempting to gain some helpful practice but find it hard when I don't understand how the equations were acquired.

i need the answer quickly
Hi im struggling to understand how you would sketch DC component Va and AC component va for the following questions. Could you show me how on both questions so i understand how to do it on different scenarios. thank you.Also is there like a universal formula i can use as every graph is not the same. Also can u show how to identify the period of each graph.
