Other terms Flashcards
what is the relationship between the ratio of voltage and number of turns in a transfomer
it is the same. V1/N1= V2/N2
what keeps ground and neutral wire seperate
Sub-panel
what has ground and neutral wire combined
Main panel box
What is a diode
a semiconductor device that allows current to flow In one direction
How does an LED work
electrical current passes through a microchip and produces light as a result of a significant electron movement. Stands for Light Emitting Diode.
what is the difference between solid and stranded wire
solid wire is made very strong and rigid but brittle, while stranded is more flexible and costs more to make.
Resistance of a material equals
(constant for metal type x length)/ Cross-sectional area
how does a GFCI work
it detects the difference in the amount of electricity flowing into the circuit versus how much is flowing out
What is stranded wire used for
smaller applications like machines, artifact, mobile devices
How does an AFCI work
It detects an electrical waveform and detects an arc fault in the current. It de-energizes circuits in the electrical appliances.
what is the solid wire used for
buildings, houses
A device used to control conduct and high current/ power in circuits. Is a type of transistor
MOSFETS ( metal oxide semiconductor field-effect transistor)
A component that connects or disconnects electrical current from a circuit
Switch
A switch that controls the opening and closing of the circuit.
Relay
A device that measures temperatures from the difference of two voltages where two junctions meet.
Thermocouple
