An electric field is a region surrounding a charged particle where other charged particles are affected
A force of attraction occurs if there is an opposite charge.
A force of repulsion occurs if there is the same charge
An electric field is the strongest near a charged particle
The electric field is weaker when it is far away
So the strength of an electric field depends upon the distance from the charged particle

The different parts of a parallel circuit are on separate branches. Therefore, each can work independent of the other.
1) Look at each circuit diagram below.2) Do you think the bulb(s) will light? If you do, put a tick in BOX A under the diagram. If not, put a cross.3) Now make the circuit using the equipment. Does the bulb light? If it does, put a tick in BOX B. If not, put a cross.4) Repeat this for all of the circuit diagrams. Then compare your predictions (BOX A) to your results (BOX B).
