CONDUCTORS AND INSULATORS
What is a circuit?
An electrical circuit is the complete loop through which an electrical current flows.
What supplies energy in an electrical circuit?
a cell or battery
What is a parallel circuit?
a circuit in which the electric current passes through two or more branches or connected parts at the same time before it combines again
What is current?
The steady flow of electrons through a circuit.
How many things must be controlled in a fair test?
One
What is a series circuit?
a circuit in which the electric current passes through each of the connected parts in turn
What is voltage?
The unit used to measure electrical energy stored in a power source
What happens to the flow of electrons as you increase the resistance in a circuit?
It slows down
In a series circuit how are the components of the circuit arranged?
In a line
What is resistance?
Slowing down the flow of electric current by trying to push it through the various components in a circuit.
List three things that increase resistance in a circuit.
Lightbulbs, motors, the length of a wire, buzzers, etc.
In a parallel circuit how are the components of the circuit arranged?
What is the difference between a cell and a battery?
A cell is a single unit. A battery is a group of cells.
What happens to the brightness of a lightbulb as you increase the voltage of the power source?
It gets brighter.
What happens in a parallel circuit if one component breaks down?
The other components can keep running
