How is energy transferred from the battery to the bulb of a torch or flashlight?
in battery it is chemical energy, from the line, it is electrical energy, through the emitter, it is the light energy.
How is the energy stored in a torch battery?
potential energy
how is energy is stored in a torch battery?
potential energy
How much energy is stored in a battery?
Depends on how big it is (button cell, car battery?) and on its chemical type.
How can you use up a source of energy when energy cannot be destroyed?
We run out of means to convert it. Coal is stored potential energy, if we use it all and the resulting heat energy escapes into space, we've lost that energy. World's water evaporates, no hydro power.

What of these energy changes occurs when a battery operated torch is switched on?
Chemical energy becomes light and heat energy.
How is energy transferred in a torch from the battery to the bulb - is it by electricity - is it by light - is it by sound - is it by thermal energy?
By electricity.By electricity.By electricity.By electricity.
What is battery's job in a torch?
powers the torch to give it energy
How is the energy stored in a torch battery?
potential energy
how is energy is stored in a torch battery?
potential energy
What forms of energy are in a torch battery?
gravitational sounificated energy
How does a torch work using the energy from a battery?
because of the electricity in the battery
Is electrical energy in a torch?
Yes, the chemical energy from the battery is converted into electrical energy.
How long will it take to make more energy when its all gone?
Energy can never be destroyed or 'ran out of', it can only be changed. E.g this is how energy is used in a torch: the chemical energy in the battery is transferred into light energy (which is useful energy in this instants), and into heat energy (which is wasteful in this instants). I may have said that heat was waisted but it can be used for other things, just not in a torch)! Hope that has answered your question.
What type of circuit would be used in a battery operated torch?
Torch equals flashlight. Battery negative connected to case switched to bulbs outside. Positive connected to the lamps bottom. Called a series circuit.
