alleryA galvanometer is converted into an ammeter of higher range by connecting:
AA high resistance in series
BA low resistance in parallel
CA capacitor in parallel only
DAn inductor in series only
Answer & Solution
Correct answer: B. A low resistance in parallel
1. To carry more current, divert most of it past the sensitive coil.
2. So a LOW resistance (the SHUNT) is connected in PARALLEL with the galvanometer.
3. The shunt value is calculated so that exactly the full-deflection current still flows through the coil at the desired range.
4. High R in SERIES converts a galvanometer into a VOLTMETER.
