electricians use to represent circuits. The symbols on a wiring diagram are
standardized so that everyone who looks at thecircuit knows what a symbol
represents. For example, an electrician in Seattle will be able to look at a
diagram with straight lines drawn by an engineer in Florida and know that
the straight lines meanwires. Simple circuit diagrams are easy to draw,
once you know the basic rules.
Things You'll Need:
Map out your circuit.Decide where you want the components of your circuit
to be placed: wires, ammeters, voltmeters, resistors, switches, light
bulbs, switches and capacitors.
Draw straight lines with your rulerto represent wires.
Draw an A inside a circle where any ammeters appear on your circuit or draw
a V inside a circle for a voltmeter. Erase the straight line at this portion
of the circuit(you do not want a straight line to run through your circle A
or circle V because this would indicate--incorrectly--that the wire is
Draw zigzags on your circuit forresistors. The zigzag looks like three
letter 'z's laying down and joined at the ends. Erase the straight line at
this portion of the circuit and replace it with the zigzag.
To draw a switchsymbol, erase a one-centimeter segment of line. Create a slide by
redrawing the one-centimeter line: attach the line to the right-hand edge of
the wire, dropping the line to the left at a forty-fivedegree angle downward.
Draw a small circle with a tick above this sliding line (the small circle with
a tick above looks a little like a light bulb).
Draw battery symbols on your circuit. Thebattery symbol is two parallel, horizontal line segments about one centimeter in length. Draw a shorter, thicker line segment between the two parallel lines, and another shorter, thicker segment...
