what are conductors?
they are components that allow the charge to pass through them
what is current?
flow of charges
what is EMF?
the potential difference across battery
what is potential difference?
it is the work done in driving a charge
what is resistance?
it is the opposition to current
state ohm’s law
resistance is directly proportional to current when physical conditions e.g temperature are constant.
what is electrical power?
it is the rate of energy transfer
what is a diode?
a component that allows current to pass in one direction only.
