Verified Answer
A DC voltmeter with a sensitivity of 20 kΩ/V is used to find the ...
 = 50 μ A
For 0 - 10 V scale Rm = 10 x 20k = 200 kΩ
For 0 - 50 V scale Rm = 50 x 20k = 1 MΩ
For 4 V reading 
vTH = 20μRTH + 20µ x 200k = 4 + 20μRTH     ...(i) 
For 5V reading 
UTH = 5μ x RTH + 5μ x 1M = 5 + 5μRTH        ...(ii)
Solving (i) and (ii)
