Answer 1

Answer:

Power supply symbols

cell symbol

Cell

Supplies electrical energy. The larger line is positive (+). A single cell is often called a battery, but strictly speaking a battery is two or more cells joined together.

battery symbol

Battery

Supplies electrical energy. A battery is more than one cell. The larger line is positive (+).

solar cell symbol

Solar Cell

Converts light to electrical energy.

The larger line is positive (+).

DC power supply symbol

DC supply

Supplies electrical energy.

DC = Direct Current, always flowing in one direction.

AC supply

AC power supply symbol

Supplies electrical energy.

AC = Alternating Current, continually changing direction.

fuse symbol

Fuse

A safety device which will 'blow' (melt) if the current flowing through it exceeds a specified value.

transformer symbol

Transformer

Two coils of wire linked by an iron core. Transformers are used to step up (increase) and step down (decrease) AC voltages. Energy is transferred between the coils by the magnetic field in the core, there is no electrical connection between the coils.

earth symbol

Earth (Ground)

A connection to earth. For some electronic circuits this symbol is used for the 0V (zero volts) of the power supply, but for mains electricity and some radio circuits it really means the earth. It is also known as ground.
