Product Code : SCL-EE-12310
Quick Answer: The Spot Reflecting Galvanometer is a sensitive physics instrument that detects small electric currents by showing the deflection of a light spot on a scale.
Last updated: October 2026
Key Features
- Detects very small electric currents in physics experiments.
- Spot reflection makes small deflections easier to observe.
- Direction of the light-spot deflection shows current direction.
- Used to find null deflection in bridge and comparison experiments.
- Supports lessons on electromagnetic torque in a current-carrying coil.
About This Product
On a stable, vibration-free bench, the light spot and scale are set up and the galvanometer is connected into a low-current circuit with correct polarity. The circuit is switched on briefly and the direction of the spot's movement noted, then adjusted until the spot reaches the required reading or null position. Students record the deflection and relate it to the current in the circuit. Export supply of the Spot Reflecting Galvanometer can be arranged to laboratories and schools in Barbados, Nicaragua, Mauritius, North Macedonia and Slovenia.
Frequently Asked Questions
Q1. How is a null point found with this galvanometer?
Adjust the circuit until the light spot comes to the null position. This null deflection is what bridge and comparison experiments rely on.
