Resistance Characteristics: Resistance

Resistance Model: Nails in an Inclined Board
PIRA Class: 5D10.40

Purpose
To use to draw analogies between the force of gravity and the electrical force (gravitational potential energy vs. electrical potential energy, lattice resistance vs. air resistance, terminal velocity vs. drift velocity)

Description
Wooden balls are rolled down a ramp with nails. The slope of the incline can represent the applied E.M.F.
NOTE: To insure that balls roll freely down board and not get "stuck" on the side nails, be sure to have the board end marked "TOP" elevated.

Equipment
Orange (golf or wooden) balls
