ΦAs decreases, “voltage” increases.

Marbles, representing current,

will roll down a ramp.

OHM’S LAW

Silver Wire

Copper Wire

Cork

Resistance increases with resistor angle

While rolling down the ramp, the marbles will

roll through lanes of

resistors.

CONCEPTUALIZATION

?

Still need to deliver marbles to the top of the

ramp, but how?

Marble elevating wheels will be

daisy chained to raise the

marbles the full height of the

ramp.
