Batteries are inserted negative to positive and the battery contains electricity which produces heat and light therefore making the battery makes the torch work
because of the electricity in the battery
Dry
You can "change" a torch battery. If you mean "charge", there are plenty of types of torch battery that can be charged. The common carbon-zinc battery, commonly used in torches in the past, is one of the few types left on the market that can't be charged.
A torch, or flashlight, typically uses a battery to power the lightbulb. When the battery is inserted into the torch, it completes a circuit allowing the current to flow from the battery to the lightbulb, which then emits light. The chemicals inside the battery convert chemical energy into electrical energy, powering the lightbulb.
When you cleaned the torch did you also put a fresh, clean battery in the torch and test the bulb to see if tht works as well
A torch (flashlight) battery is a dry cell, and is not designed to be recharged.
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
3v battery is used direct current
The medium through which the emitted light of a torch passes will not affect the battery life of the torch. The battery life of the torch will be the same if you are shining it through air, glass, water, or anything else.
More likely used for a toy car.
powers the torch to give it energy
they are two different types of batterys, the car recharges it's battery as you drive, that battery is a rechargable battery. the torch does not have a rechargable battery but you can add one to it.
