When a toy flashlight does not work, which two parts should you check and how are the parts related?

My homework; Predicting, communicating





example: Your little sister tries to turn a toy flashlight on one evening, but it does not work. Which two parts shoudl you check? How are the parts related?|||There are 3 things that could be wrong not just 2.


The light bulb is burned out, the light bulb is the end of the line for the energy released by the battery.


The battery could be bad, the battery stores energy required to make technology work.


The 3rd thing could would be the wires connecting the battery and the light bulb, if the wire is no longer between the 2 there is no path for the energy (electrons) to travel from the battery to the light bulb.|||batteries and the bulb. Batteries supply the power for the bulb but if the light is burnt out it can't function, so one w/o the other is useless.|||Replace the batteries and then if that does not work, check the bulb. Make sure that the little plate under the batteries is actually in contact with the batteries when they are loaded.|||The batteries and the bulb.|||the electric current and the circuit


all the metal parts (spring, fliament in bulb, switch, and metal contacts) are the circuit.


batteries supply the current.|||In answer to your question you need new batteries or a new bulb or both. I would check them both if the batteries don't work.
