Learning Goals: Describe how to create a circuit. Understand the role voltage and current play in a circuit.
Requirements of a Circuit • Closed conducting loop (ex: usually wire) • Power or energy source, also called an emf (ex: batteries, generators, power outlet) • A load, something that uses energy (ex: light bulb, resistors, any electrical appliance) http://phet.colorado.edu/en/simulation/circuit-construction-kit-dc
Types of Circuits Closed Circuit – a complete conducting loop through which charge can travel Open Circuit – a path where charge does not flow Short Circuit – a closed circuit that does not contain a load (very dangerous)
As work is done against gravity the barbell gains potential energy. Work Gravitational Force
As work is done against the electric force the charge gains potential energy. Electric Force Work
