To convert a galvanometer into an ammeter |
a very small resistance is added in series with the galvanometer a high resistance is added in series with the galvanometer a very small resistance is added in parallel with the galvanometer a high resistance is added in parallel with the galvanometer |
a very small resistance is added in parallel with the galvanometer |
The correct answer is Option (3) → a very small resistance is added in parallel with the galvanometer To convert a galvanometer into an ammeter, it must be able to measure large currents without being damaged. This is done by connecting a very small resistance in parallel (called a shunt) so most of the current bypasses the galvanometer. Correct option: a very small resistance is added in parallel with the galvanometer |
