9.2 Series and parallel circuits Flashcards
Circuits and their components
1
Q
What is a series circuit? Explain some of its characteristics.
A
A circuit with just one loop. The electrons have only one way to go, which means the current is the same all the way around the circuit.
2
Q
What is a parallel circuit? Explain some of its characteristics.
A
A circuit with more than one loop, so the current may split up, but the total current stays the same.
3
Q
What is current?
A
A flow of electric charge made up of electrons
4
Q
How is current measured?
A
In amps using an ammeter.
5
Q
What is the difference between a cell and a battery?
A
Two or more cells together are called a battery.
6
Q
What is the function of a diode?
A
A diode is a component that allows current to flow in only one direction.
