Basic Electronics Quiz

What is electricity?

• A material that is neither a good conductor nor a good insulator; its electrical conductivity can be precisely altered by a manufacturing process.

• A form of energy made up of charges that can produce light, heat, or motion.

• is the measure of the attraction that an atom has for the electrons orbiting about its nucleus.

• Is the building blocks of our universe.

What is Ohm's Law?

• Is the measure of the attraction that an atom has for the electrons orbiting about its nucleus.

• A form of energy made up of charges that can produce light, heat, or motion.

• Opposition to the flow of current is termed resistance. The fact that a wire can become hot from the flow of current is evidence of resistance. Conductors have very little resistance. Insulators have large amounts of resistance.

• The practical unit of resistance is the ohm designated by the Greek letter omega: Ω.  A resistor is an electronic component designed specifically to provide resistance.
