physics Flashcards
what’s an electric circuit
its a closed pathway to where electric charges flow
what are the basic parts of an electric circuit
energy source conductor load
whats a battery
. A battery changes chemical energy stored inside the battery into electrical energy.
whats a solar cell
is an energy source that changes light energy into electrical energy
whats inside a power plant
form of energy such as chemical or nuclear energy is changed into mechanical energy.
whats an electric generator
The electric generator changes mechanical energy into electrical energy.
how do they deliver energy
through power transmission Lines
- Materials in which electric charges can move easily are called
electric conductors
whats a good conductor
metals
electric wires are often mad of
copper
- To protect people from harmful electrical shocks
copper wire is often covered with an insulator. An electrical insulator is a material, such as glass, plastic, or rubber, through which electric charges cannot move easily.
whats a load
a device that uses electrical energy to operate
how does a electric circuit work
The conductor connects the energy source to the load. The load converts electrical energy into other forms of energy.
- Examples of loads
radios , lightbulbs , computers , motors
what is one tool that can be modeled electric circuits
circuit diagraphm
