Physics- Grade 9 electricity
Electricity-✔✔The set of physical phenomena associated with the
presence and motion of matter that has a property of electric charge.
Parallel circuit-✔✔A circuit that has more than one pathway for electrons
to follow.
Series circuit-✔✔A circuit that has a single pathway for electrons to follow.
Electric charge-✔✔The ability of electric charge to move, which is
essential for the utility of electrical energy.
Static electricity-✔✔The buildup of positive or negative charge on
materials.
Current electricity-✔✔The energy of steadily moving electric charge, used
by electric devices such as lamps and computers.
Circuit-✔✔A pathway for electrons to follow, allowing the flow of electric
current.
Resistance-✔✔A measure of how much an object opposes the flow of
electric current.
Equation of voltage is?-✔✔V= e/q units
Equation of current is?-✔✔I= q/t rate
Energy mass-✔✔it has no mass
Type of energy in a battery-✔✔chemical energy
