it is a complete pathway that allows electrons to flow
what materials make static charge?
insulators
what is conventional current?
Benjamin Franklin's theory that static charge is a fluid and positive charge is an excess of fluid and negative charge is a lack of fluid. This theory is outdated
what is Ohm's law?
V=IR
what are the 2 methods for determining resistance?
using an ohmmeter or attaching an ammeter and a voltmeter then using Ohm's law
what is a resistor?
an electrical component with a specific resistance. It can be used to control current and potential difference.
current electricity
the continuous flow of charge in a complete circuit. Moving charge (not static)
electric current
the amount of charge passing a point in a conductor every second
power
the rate of change in energy
power rating
amount of electrical transformed per second in a load. For example, 60 watt = potential to convert 60 joules of electrical energy into 60 joules of another kind of energy in one second.
power formula
P=VI
energy consumption
amount of electrical energy a device consumes over a certain period of time
energy consumption formula
what does one joule equal
1j = 1 watt x 1 second
how many seconds are in an hour?
3600 seconds
what is the acronym for the resistance band colours?
