"tbe buffer"

Simple circuit module.

Enhance your circuits with sound.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

Demonstrates static electricity's attractive and repulsive forces using a pendulum electroscope.​

Demonstrate the Lorentz force and calculate the charge/mass ratio of an electron.

Investigate the deflection of electrons.

Guinea and feather tube apparatus with 6 induction coils connected in series.
