Activity 5.1

Most of you have identified the problems in the torches that were assigned to your groups respectively, but we were unable to consolidate the 3 different problems in class today. Here is a consolidation of possible problems:

Problem 1: The batteries are arranged wrongly.
Action taken: Arrange the batteries correctly.
How is it solved? The batteries are arranged in the correct order for electric current to flow through the circuit.

Problem 2: The bulb is broken / fused.
Action taken: Replace the bulb.
How is it solved? A working bulb allows electric current to flow through it.

Problem 3: The switch is loose.
Action taken: Tighten the switch.
How is it solved? The switch is connected properly to the rest of the circuit.

A torch is an electrical system. For a torch to give off light, all the parts of the torch must work together.
