Part 5: Calculate the value of shunt resistance.

50(10-3^ )A = V (^) s/100Ω

  • V (^) s = 0.005 V
  • 10(10-3^ )A = (0.001V)/(100 Ω + Rs )
  • 10(10-3^ )A * (100 Ω + R (^) s) = 0.005V
  • 1V + 10(10-3^ )A*(Rs ) = 0.005V
  • 10(10-3^ )A*(Rs ) = -0.995V
  • Rs = (-0.995V)/ (10(10-3^ )A)

R (^) s = -99.5 Ω

Part 6: Develop a formula for calculating the internal ammeter resistance.

For procedure step 5, CH1 is in parallel with RM2 therefore the voltage is the same. That means that we can exclude M 2 from the formula. This yields the relationship,

V (^) CH1 = (M 3 ) * (R (^) M2 )

When the values for each reading are substituted into the formula the results are as follows:

Readings Rm (Ohms) 1 226 2 217. 3 208. 4 181. 5 82
