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

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

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
