Problem 56PE

Unreasonable Results (a) What resistance would you put in parallel with a 40.0-Ω galvanometer having a 25.0-μA sensitivity to allow it to be used as an ammeter that has a full-scale deflection for 10.0-μA ? (b) What is unreasonable about this result? (c) Which assumptions are responsible?

Step-by-Step Solution:
Step 1 of 3

Solution 56PE

a)

From below mention formula calculate parallel resistance,

R = (r) the parallel resistance is 66.7 b)

The calculated parallel resistance value is large but it should be small in range of  10-3  to 10-6. Hence this is unreasonable about this result.

c)

Here, full scale deflection value  10 is responsible.
