Series and Parallel Circuits

It is a device used to power electrical circuits. It has two terminals; positive and negative. The terminal marked negative is the source of electrons, that when connected to a circuit delivers energy.

It is a flexible strand of metal, usually made of copper. They are used for establishing electrical conductivity between two devices of an electrical circuit.

It is a device that produces light from electricity. This turn the electricity to light by sending current through a thin wire called filament.

This circuit is made by connecting the end of one device to the beginning of another.

This circuit has the same terminals of both devices that are connected together

Select all the characteristics of a series circuit.

• The same amount of current flows through all the components
• components are arranged in a line
• If one component breaks down, the whole circuit will burn out.
• The current flowing through each component combines to form the current flow through the source.
• components are arranged parallel to each other

Select all the characteristics of a parallel circuit.

• The current flowing through each component combines to form the current flow through the source.
• components are arranged parallel to each other
• Other components will function even if one component breaks down, each has its own independent circuit
• The same amount of current flows through all the components
• components are arranged in a line

This device protects us from receiving electric shocks from faults in the electrical devices we use in our home.
