Electricity : a form of ENERGY INTERACTION BETWEEN + and - charges Static Flow (BUILT UP CHARGES) (MOVING CHARGES) Cotton Shirt Wool Sock Plastic Wrap Plate Cloud Ground What are some things that FLOW?
What are some things that FLOW? Flow (MOVING)
We need a SOURCEof energy for FLOW to occur Source: Source: Source:
Electricity : a form of ENERGY INTERACTION BETWEEN + and - charges Static Flow (BUILT UP CHARGES) (MOVING CHARGES) Protons or Electrons Electron Flow ? Insulator Conductor
Sources of Electrical Energy & Flow Date: Source: Device that supplies electrical energy Ex: Battery Outlet
How Does a Battery Work ? + Positive Terminal CHEMICAL ENERGY Chemical Changes Paste ELECTRICAL ENERGY • - NegativeTerminal
How Does a Battery Work ? Due to a chemical reaction in the battery paste, the negative end builds up an excess of electrons. Electrons move from the negative terminal to the positive terminal. Chemical Energy Electrical Energy
Potential Difference 120 V 1.5 V
Potential Difference: change in the energy of a • unit of charge after passing through a source or load • Also called VOLTAGE

Potential difference (V) is measured in Volts (V). Voltmeter:the device that measures the potential difference between TWO POINTS in a circuit
A constant flow of electrical energy can drive a • steady current (FLOW of charges).
