The multiplier resistance on the 50 V range of a DC voltmeter that uses a 500 Ω shunt resistance can be calculated using the formula:
Multiplier resistance = (Full scale voltage - Shunt voltage)/Shunt current
The full scale voltage is 50 V and the shunt resistance is 500 Ω. Let's assume that the shunt voltage at full scale is negligible. The shunt current can be calculated using Ohm's law:
Shunt current = Full scale voltage/Shunt resistance
= 50 V/500 Ω
= 0.1 A
Now we can calculate the multiplier resistance:
Multiplier resistance = (Full scale voltage - Shunt voltage)/Shunt current
= (50 V - 0 V)/0.1 A
= 500 Ω
Therefore, the multiplier resistance on the 50 V range of a DC voltmeter that uses a 500 Ω shunt resistance is 500 Ω.
