Grade 9 Circuit Symbols And Functions

Really useful to memorise these before we start using them.

Grade 9 circuit symbols and functions. You will also revise simple circuits circuit diagrams and connecting cells and lamps and switches in series and parallel. Recognise and explain the function of circuit symbols convert units of measurement identify and read resistor colour codes. Circuit symbols and description. Let us learn about some important components of circuits and their symbols in a circuit diagram.

Generates current as a function of voltage or current of other circuit element. Circuit symbols are used in circuit diagrams which show how a circuit is connected together. Use the correct circuit diagram symbols. Component symbols and simple circuits.

In this chapter you will revise the work you did on electrical systems and control in grade 8. Type of assessment summative purpose of assessment to assist students in understanding circuit symbols and their function units of measurement and their value. Has very high resistance. Note that the cells are in series.

In its symbol the larger terminal is positive whereas the smaller one is the negative terminal. Use eye protection when experimenting on your own circuits. Has near zero resistance. Use mydaq digital multi meter dmm to test mysnap components if they appear to be damaged or not working properly.

The symbol for an spst switch figure 4. It provides the source of current. Always remove power if circuit does not perform properly and then use mydaq dmm to check circuit for shorts or. When i first started working with printed circuit board schematics i thought i knew everything to know about identifying electronic components circuit symbols and functions in a schematic but i was routinely surprised.

Unfortunately the parallels of parenting are everywhere. Single pole single throw switch spst figure 3. Always check circuits before turning on power. Draw the circuit diagram of the doorbell circuit in the photograph.
