Explore the difference between insulators and conductors in electric circuits, where current flows from the battery through wires, into the light bulb, and back. Learn about resistance and how it impacts electron flow, and discover the relationship between voltage, current, and resistance. Unravel the concept of resistance as a hindrance to electron flow and the factors affecting it.

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 Electric lamp (glowing) Electric lamp (not glowing) Conductor lets electrons flow Insulator doesn’t let electrons flow
Insulators and Conductors Atom Insulators hold electrons close like a dog on a leash Insulators let electrons flow like dogs running free Conductors let electrons flow like dogs running free
Resistance Higher Resistance Lower Resistance • Resistance: is like resistance to water flow in a hose. Larger diameter hose -less resistance, longer hose –more resistance • Voltage like pressure, current like flow • 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
