By: Robert Murrian David Okeke Brandon Mast __//** Vocabulary: **//__ Load- The component that does the work Schematic- A diagram which uses schematic symbols for components to represen t an electrical circuit Secondary cell- A battery that can be recharged Primary Cell- A battery that can not be recharged Voltage source- A circuit or component which produces an EMF, and supplies that EMF to another electrical Circuit Voltage rise- Voltage introduced into a circuit Voltage drop- The potential difference across a component through which current is flowing Earth ground- A connection from a piece of equipment to a metal pipe that is driven into the ground. Chassis ground- The reference point for a piece of equipment when the metal frame provides both a common reference, and a common return for the equipment Frame ground- The reference point for a piece of equipment when the metal frame provides both a common reference, and a common return for the equipment

**//__ Chapter Review: __//** __//**INTRODUCTION**//__: This chapter is about the application of current and voltage into a circuit. It covers the battery, how they are connected and what types there are. It covers voltage rise and voltage drops and the difference between the two. __//Voltage Rises and Voltage Drops//__: Voltage rise is the voltage being applied to the circuit while the voltage drop is the voltage used up by each componet. Voltage rise will always equal voltage drop no matter what.
 * //__THE ELECTRICAL CIRCUIT__//**: The basic circuit consist of a power source a conductor and a load. The power source in a DC circuit is usually a battery which supplies the voltage to the circuit. The conductor is what carrys the electrons through the circuit. and the load is what does the work. Each object in the circuit has a schematic symbol. While you may draw the circuit in detail a schematic symbol is an easy representation of a componet. They are used to keep things more simple in complex circuits.
 * //__BATTERIES__//**: A battery is the basic power source in a DC circuit. There are 2 types of batteries a primary cell (which cannot be recharged) and a secondary cell (which can be recharged) they all store energy in a chemical form and produce EMF. Some primary cell batteries are the Dry cell battery which is what we use in most circuits examples of dry cell batteries are AA, AAA, D, 9V. An example of a Secondary cell is a Lead-Acid battery that is used in cars. The electrolyte is made of a mixture of sulfuric acid and water. They can charge themselves by an electircal current. Batteries can be connected in many ways. You can have series aiding connections which increase the output voltage. 1.5v in series aid with another 1.5v will increase the voltage to 3.0volts. Also there is series resisting which does the opposite as a series aiding. If a 1.5v is in a series opposing with another 1.5v the total voltage would be 0.0volts. You can connect them in parallel whic increases the current capacity.

Ground- or earth is used to reference with its zero potential Chassis ground- metal frame which the circuit is built upon Circuit ground- uses electrical equipment as ground
