1. Insulators and Conductors
Electric Circuit
Current provided by battery flows through wire, into the light bulb, through another wire, and back to the battery.
Current: flow of electrons
Conductor lets electrons flow
Insulator doesn’t let
electrons flow

2. Insulators and Conductors
Insulators hold electrons close like a dog on a leash
Atom
Conductors let electrons flow like dogs running free

3. R - Resistance  - Density L - Length A - Area
Higher Resistance
Resistance: How much the material resists the flow of electrons
R = V / I
The higher the resistance, the slower the flow of electrons, the smaller the power output
R = ( x L) / A
R - Resistance  - Density L - Length A - Area
Lower Resistance
