Calibration of the Galvanometer: Observation Experiment
Aim
To calibrate the galvanometer
Prior Knowledge
- Electric current.
Description of the Experiment
A battery is connected in series with a resistor and the galvanometer. The galvanometer is thus wired to detect currents in the circuit. The direction of the current flow is indicated by the chalk marks indicating which terminal of the galvanometer is the positive one and which is the negative one. Note which way the galvanometer deflects, corresponding to the particular direction in which the current is flowing.
