Question

You have three light bulbs, a battery, and a switch.a) Using proper electrical symbols, draw a series circuit to show how to connect the three bulbs and the switch to the battery. Make sure that the switch is placed in such a way as to control the flow of current to the entire circuit.b) Repeat the steps in question 9 (a), but this time draw a parallel circuit.

Answer 1

a)

Let's represent the bulbs using resistors. Since the bulbs are in series, the endpoint of one resistor is connected to the start point of the next resistor.

Drawing a diagram where all elements are in series (they all have the same current), we have:

b)

Since the elements are now in parallel, the start point of each element is the same and the endpoint of all elements (except the switch) is the same.

Drawing the diagram, we have:
