You are asked to design a circuit that will turn on a set of lights. You are given the following materials:

- string of lights

- battery

- wires

- rubber

- switch

How would you design a circuit that allowed the lights to turn on and off? Explain.

See the explanation below

Explanation:

In order to perform the circuit, we must use the following elements:

- string of lights

- battery

- wires

- rubber

- switch

First, we connect two wires each in one of the terminals of the battery. One of the wires is connected to the string of lights, the other extreme of the string of lights is connected to another wire, this wire is connected to one of the switch terminals and the other terminal is connected to the other terminal of the battery.

This can be seen in the attached image. When we operate the switch we can turn on and off the lights.

When the circuit closes, the lights work. The current flows through the wires interconnect the elements.
