Study Notes
Circuit Diagrams
-
A circuit is a continuous loop of wires, one or more loads, and a switch
-
Circuit diagrams are a standard way of drawing electrical circuits
-
Symbols are used to represent different types of components in a circuit
-
Table 1 lists some common circuit symbols
-
When drawing a circuit diagram, you are typically given a description of the circuit and the devices within it
-
Identify components and draw their symbols from the written description
-
The longer line (one electrode) is positive, while the shorter line (the other electrode) is negative.
-
Most circuits have more than one load which may be connected in series or parallel
Series Circuits
- In a series circuit, the flow of electrons follows only one path
- Loads are connected end to end in a chain, one after another in a continuous loop
- If one device in the circuit stops working, the entire circuit will stop working.
- Example: A toaster and kettle are both connected to the same outlet. If the fuse for the outlet blows, neither device will work.
Parallel Circuits
- In this type of circuit, electrons can flow more than one way
- Loads are connected in branches so that there are two or more paths for electrons to flow
- If one device in the circuit is disconnected, the other devices continue to work
- Example: The stove and refrigerator are two loads in parallel and are regulated by fuses. If the stove's fuse blows, the refrigerator will continue to work.
