Science - year 9 - electricity
What is electricity?-✅Is the flow of electrons from 1 place to another.
Is electricty a secondary or primary energy source-✅Secondary source, it
is converted form something else (sunlight, coal, oil)
✅An accumulation of charge
What is static electricity?-
What is current electricity?-✅A flow of electrons
What are conductors and an example-✅Low resistance to Allow the flow
of eletricity (eg metal)
What are insulators?- ✅High resistance to Prevent the flow of electricity
(eg rubber)
What is a simple circut- ✅Consists of a power source, a conductor, and a
load (like a lightblub.
Open circut- ✅broken path; when the switch is off
Closed circut-✅complete circut - electricty only flows in closed circuts
Power souce example-✅Battery
Conducters example in the circut-✅Wires
Resistors example-✅A light bulb
Electricity is measured in-✅Volts for potential differeces, amps for current
and ohms for resistance
Where does a voltmeter go in a circuit?- ✅across a component outside of
the circut
