Why is static electricity not very useful as a power source?
All the energy is released very slowly.

What is a LOAD in a circuit?
A device that uses magnetism.
A device that uses electricity.
A device that uses solar energy.
In a wall socket, why are there a minimum of two openings?
because the electrons shoot out of both holes
because the electrons need somewhere to go
A switch..
Makes the matter drop below 32 degrees
Controls whether an device is on or off
Permanently stops the flow of electrons
How does a SWITCH work?
The switch increases the amount of electrons flowing in the wires.
The switch makes the electrons in a wire move faster.
The switch opens or closes the circuit.
For electric current to flow, do you need a closed or open circuit?
