Electronic Systems

Solderless Circuit Board

A device that allows you to assemble electronic circuits without the use of solder

Resistor Color Code

A method of indicating the resistance value in ohms; color bands are associated with a number that allows for quick and easy resistor value reading

+/- 1%

Brown Percent Tolerance

Resistor

Device used to regulate the flow of current; one of the most fundamental electronic components

Voltage

Forces that cause electrons to flow through a circuit; measured in volts

Ohm's Law

Gives relationship between voltage, current, and resistance in electronics

=/- 5%

Gold Percent Tolerance

I=V/R

If current is missing...

R=V/I

If resistance is missing

V=I*R

If voltage is missing...

Electric Current

Movement of millions of electrons through a wire; measured in amperes(amps)

=/- 2%

Red Percent Tolerance

+/- 10%

Silver Percent Tolerance

Electronics

Study and use of electrical device who's operation is controlled by the flow of electrons

Resistance

The opposition to current flow; measured in ohms
