## terms list

watt

measures electrical power (energy consumed)

ampere

measures electrical current (strength)

volt

measures electrical pressure

ohm

measures electrical resistance

hertz

measures frequency of alternating current

short circuit

a circuit with no resistance

ohm's law

the relationship between voltage, amperage and resistance

amperes = volts / ohms

ohm's law (write it out)

ohms = volts / amperes

find ohms from volts and amperes

volts = amperes * ohms

find volts from amperes and ohms

amperes = volts / ohms

find amperes from volts and ohms

law of electric power

law dictating the amount of power consumed by a device

watts = volts * amperes

law of electric power (write it out)

step-up transformer

two electromagnets that increase the voltage of the current

step-down transformer

two electromagnets that decrease the voltage of the current

generator

device that changes kinetic into electric energy

motor

device that changes electric into kinetic energy

rotor

a spinning electromagnet

stator

a stationary magnet

capacitor

a device that briefly contains electricity

resistor

a device that creates resistance to the flow of electrons

transformer

a device that changes voltage and amperage of a current

series circuit

a circuit where all moving electrons pass through every part of the circuit

parallel circuit

a circuit where the voltage is the same at all points in the circuit

total resistance

added resistance of all points in the circuit

series-parallel circuit

combination of the two basic circuit types

dopants

chemical that determines whether silicon will be an insulator or a conductor

transistor

devices that can switch a current, regulate its flow or amplify a current

diode

devices that allow a current to travel in only one direction

rectifiers

devices that transform AC into DC
