2. Review of the Lesson

The Electrical Potential Energy is increased by the pump. To create this potential energy we need an external source.

Examples of external sources:

Dry Cell- Convert Chemical to electrical

Solar Cell- Convert Light energy to electrical

Generator- Driven by moving water or wind to create to electrical energy

This closed loop is called an electrical circuit

• Voltage is an “electric pressure that can produce a flow of charge, or current within a conductor.

• When the ends of an electrical conductor are at different electric potentials, charge flows from one end to the other.

• Charge flow when there are potential difference, or difference in potential (voltage), between the ends of the conductor.

• The flow of charge will continue until both ends reach a common potential. When there is no difference in potential, there is no longer a flow of charge through the conductor.

• To attain a sustained flow of charge in a conductor, some arrangement much be provided to keep one end at a higher potential than the other.

1. Charge of flows when there is a _________________ between the ends of a conductor.

2. Explain how the sustained flow of charge is analogous to the flow of water from a higher reservoir to a lower one, as show in the illustration below.

• In schematic diagram, resistance is shown by zigzag line, and ideal resistance=free wires are shown with solid straight lines. A battery is represented with a set of short and long parallels.

• Electric circuits are frequently described by simple diagrams, called schematic diagrams, using special symbols to represent certain circuit elements.
