Source
This represents the source of the electrical energy
Where the electrons are coming from and to an extent the direction that they are moving in.

Conductor
This is the wire through which the current flows
14
Load
Items along the circuit that convert electricity into other forms of energy
light bulbs, motors, heaters, and speakers
Which is also referred to as a resistor

Measuring Current
18
If you were to describe the current you might state the number of litres of water that flow past a certain point every minute. Similarly, scientists describe electric current as the amount of charge that passes a point in a conducting wire every second. The symbol for current is I. Electric current is measured in amperes (A) or milliamperes (mA)
19
An instrument used to measure very weak electric current is called a galvanometer. Larger currents are measured with an ammeter or
milliammeter. The symbols for these instruments are a circle with “G,”
“A,” or “mA”
