Grade 9 Circuit Symbols And Functions

The actual layout of the components is usually quite different from the circuit diagram.

Grade 9 circuit symbols and functions. A typical light circuit with anenergy source switch and lamp. Components of circuit diagram. Circuit symbols and description. Really useful to memorise these before we start using them.

In this chapter you will revise the work you did on electrical systems and control in grade 8. Always remove power if circuit does not perform properly and then use mydaq dmm to check circuit for shorts or. In its symbol the larger terminal is positive whereas the smaller one is the negative terminal. Generates voltage as a function of voltage or current of other circuit element.

Use eye protection when experimenting on your own circuits. Always check circuits before turning on power. Use mydaq digital multi meter dmm to test mysnap components if they appear to be damaged or not working properly. Circuit symbols are used in circuit diagrams which show how a circuit is connected together.

Generates current as a function of voltage or current of other circuit element. 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. The symbol for an spst switch figure 4. It provides the source of current.

Has very high resistance. Grade 9 resistors grade 9 draw circuit symbol for a potentiometer grade 9 light emitting diode grade 9 light dependent resistors and thermistors grade 9 systems grade 9 transistors grade 9 computers and binary numbers grade 9 problem solving grade 9 electrical problem grade 9 capacitors grade 9 symbols for and functions of electric components. Note that the cells are in series. Type of assessment summative purpose of assessment to assist students in understanding circuit symbols and their function units of measurement and their value.

Use the correct circuit diagram symbols. Draw the circuit diagram of the doorbell circuit in the photograph. 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.

Let us learn about some important components of circuits and their symbols in a circuit diagram. Single pole single throw switch spst figure 3.
