functions of hydrolics Flashcards
what is a resistor
a device that offers resistance to the electron
most insulators are compounds of?
2 or more elements
what does D/C stands for?
Direct Current
what does MALT stands for?
Material, Area, Length and Temperature
what does A/C stands for?
Alternating Current
Current is electrical?
Electrical flow
what is ESD
Electrostatic Discharge
all materials are composed of
atoms
define coulomb’s law
opposite charged particles attract, like charge repel
how many electrons are in the outer ring of a conductor
1-3 qualifies for a conductor
electrons in the outer ring of the atoms are called
valence electrons
electrons have what kind of charge?
negative charge
define resistance
opposition to the flow of electrons
what happens when two or more atoms of different elements come what happens?
compounds are form
what’s a conductor?
a material that allows electricity to flow through them
what’s a insulator?
an insulator is a non conductor, they normally have five or more electrons
define voltage
voltage is the pressure or force that causes electrons to flow
define current
current is the amount of electron flow in a conductor
what are the components of an electrical circuit
the power source, the load, conductors and the control.
name the types of circuits
series, parallel, series-parallel circuits
explain a series circuit
only has one path of current flow
explain a parallel circuit
has two path of current flow
