About This Product
With its centre-zero scale the galvanometer shows which way a current flows, so students can balance a Wheatstone bridge or meter bridge by moving the jockey until the pointer reads zero. It is also used to show the brief currents induced when a magnet moves in a coil.
Frequently Asked Questions
Why does the galvanometer have a centre-zero scale?
The 30 - 0 - 30 scale lets the pointer swing either way, showing the direction of current and making the null point easy to find.
