Electric circuits vocab
Terms in this set (15)
energy associated with the movement of charged particles from one place to another.
when a conductor—something that electrons can move through—makes a path from one end of a battery to the other, or from one side of an outlet to another, electrons begin to flow through it
The pathway taken by an electric current
the continuous flow of moving electrons through wires. They do different kinds of work by converting their electrical energy to another type of energy.
When a circuit's loop is complete
If a circuit's loop is not complete for any reason, then it is called an. Open circuits prevent the movement of electrical energy.
Every circuit must have a source of electrical energy, such as a battery, which pushes the electric current around the circuit.
Every circuit must have a material that connects the parts of the circuit together and carries electric current. Often, this material is metal wire wrapped in a coating of plastic or rubber.
The load, or receiver, such as a light bulb or appliance, changes electrical energy to another kind of energy like light, heat, motion, or sound.
Circuits usually have switches. The switch completes the circuit and allows current to flow if closed but prevents current from flowing if open. Sometimes, the switch is not shown in circuit diagrams.
A fuse is a thin piece of metal that melts and makes a gap in the circuit if the flow of energy is too great. This interrupts electricity flow, and any receiver attached to the circuit turns off. Circuit breakers perform the same function as fuses. Fuses and circuit breakers help prevent electrical fires.
when all parts of the circuit are connected in a single loop.
receivers are connected to different branches.
a material that transfers an electric current well. Common conductors of electrical energy include: copper, aluminum, silver
material that does not transfer an electric current. Ex. Rubber, glass,
