Question
Find the resistance that must be placed in parallel with a $10.0 \Omega$ galvanometer having a $100 \mu \textrm{A}$ sensitivity to allow it to be used as an ammeter with: (a) a 20.0-A full-scale reading, and (b) a 100-mA full-scale reading.
1. $5.00 \times 10^{-5} \Omega$
2. $10.0 \textrm{ m}\Omega$
