Electric Circuit A circuit is a complete, closed path through which electric charges flow

Electric Circuit A circuit is a complete, closed path through which electric charges flow (circle). Parts of a circuit – load – device that uses electrical energy source – battery or outlet wire - connector

Opening and closing a circuit Switch – when closed, the electricity flows when open,

Opening and closing a circuit Switch – when closed, the electricity flows when open, the electricity in that circuit stops because it isn’t complete

Types of Circuits Series - a circuit in which all parts are connected in

Types of Circuits Series - a circuit in which all parts are connected in a single loop or branch

Characteristics of a Series Circuit 1. All loads must be working for the circuit

Characteristics of a Series Circuit 1. All loads must be working for the circuit to work. 2. Every load reduces the amount of current going to all the loads (add a bulb, they all get dimmer). 3. All loads share the same current so they all have the same brightness. 4. Easy to wire.

Examples of Series Circuits 1. The automatic doors at the grocery store. 2. Very

Examples of Series Circuits 1. The automatic doors at the grocery store. 2. Very old Christmas lights where one bulb goes out and they all do. 3. Bank and home alarms 4. Computer circuits.

Parallel Circuit Is a circuit in which different loads are located on separate branches.

Parallel Circuit Is a circuit in which different loads are located on separate branches.

Characteristics of Parallel Circuits 1. More difficult to wire. 2. Each branch functions by

Characteristics of Parallel Circuits 1. More difficult to wire. 2. Each branch functions by itself so if one load fails, the loads on other branches still work. 3. Each branch has a full amount of current so the loads on that branch receive the full amount. (Each light bulb is as bright as the others).

(1) Series or (2) Parallel a. b. c. d. e. f. g. h. i. Loads are wired on multiple branches Loads are wired on a single branch or loop If one load goes out all the loads go out Light in your house If one load goes out all the others still work Home alarms Computer circuits All loads are just as bright as the others One load brighter than the others
