Electricity Notes
Electricity is the flow of electrons. The main focus on this topic is making a complete circuit, series circuits and parallel circuits. As you learned when you completed the labs for this unit, there are two connection points on a bulb that must be connected with the two working ends of a battery for the current to flow and a light to light.
In a series circuit, each part must be connected in a line or row. Series circuits produce brighter lights when the batteries are connected that way. The disadvantage of series circuits with lights is that when one light goes out they all go out.
In a parallel circuit, each part is connected so that the object is in a side-by-side configuration. Parallel circuits do not produce brighter lights when the batteries are connected that way. The advantage of parallel circuits with lights is that when one light goes out the rest stay on.
