Electricity Flashcards
Name three parts of an atom
Shell nucleus electron
Name three main parts of a circuit
Power source, switch, conductor
What port does the black lead to go into
Common
How many free electrons do conductors have
Less than five in the outer shell
How does a voltage meter measure voltage
It measures the difference between common and V
In ohmmeter shows O.L when measuring resistance that means
The resistance is over limit
If a voltage meter displays 0.00 across a switch in the on position
No difference is present
What is the smallest part of any substance called
Molecules
What are molecules made of
Atoms
Substances that allow easy flow of electrons are called
Conductors
Substances that resist the flow of electrons are called
Insulators
The modern theory of magnetism is based on what
Domain theory
Definition of voltage
A difference in charge or an accumulation of charges
Definition of amperage
Moving charges
