FIVE:

CIRCUITS

circuit energy I

Frame EL1

current and resistance

Frame EL2

resistors in series and parallel

Frame EL3

current, particles and energy transfer

Frame EL4

circuits, difference and flow

Frame EL5

current, resistance and voltage

Frame EL6

the logic of equations

Frame EL7

defining and calculating resistance

Frame EL8

a linear graph

Frame EL9

not-so-linear graphs: hot wire

Frame EL10

not-so-linear graphs: diode

Frame EL11

so, what flows?

Frame EL12

‘charge’ flows

difference creates flow

Frame EL13

Frame EL14


counting charge (it’s easier than counting electrons)
