A galvanometer coil has a resistance of 10 \(\Omega\) and the meter shows full-scale deflection for a current of 1 mA. The shunt resistance required to convert the galvanometer into an ammeter of range 0 - 100 mA is about:
- 0.1 \(\Omega\)
- 10 \(\Omega\)
- 1 \(\Omega\)
- 0.01 \(\Omega\)
Answer
(A) 0.1
