What is the power of an ordinary torch cell?

depending on what type of torch itis, an ordinary hand held slim one is around 10 volts in ONE call and there are around 600 cells in the torch.. hope this helps


Why doesn't your torch work?

my torch does work though...


What is common in wet and dry cell batteries?

All batteries contain something called the electrolyte. In wet cell batteries the electrolyte is a fluid, while in dry cell batteries it's a paste or a gel.Wet cell batteries may need to be stored and used upright, while dry cells can be handled any old how.A Dry-cell battery is the kind of battery that you find in sizes "AAA, AA, C, 9 Volt' and so on.A Wet-cell battery is the kind of battery you find in cars or trucks(as said on One_difference_between_dry-cell_batteries_and_wet-cell_batteries_is_that)in dry cell the electrolite is solid and in wet cell in liquid stateA wet cell battery is a battery that contains a liquid or jell acid solution such as an automobile battery. A dry cell is a battery such as a EE flashlight battery or any battery such as one for a computer, cell phone, etc.Dry cell is reaction between solid compounds and a anode whereas in wet cell it uses liquid.In a wet cell there is a chemical reaction between a thin sheet of zinc and sulfuric acid. This reaction then causes electrons to gather on the zinc giving it a negative charge while a copper sheet is given a positive charge.The zinc and copper are connected by a conductor so when electrons move from the zinc to the copper an electrical current is generated.In a dry cell the outer case is made of primarily zinc which gain a negative charge through a chemical reaction.On one end there is a raised spot which is the negative terminal.There is also a carbon rod that runs through the middle of the dry cell and is connected to the positive terminal.When the two terminals are connected by a conductor, electrons move through it generating an electrical current.


What safety precaution should be taken when using a torch inside or near a building?

Bucket of Water


What is an electric torch?

A torch consist of a plastic casing,a bulb ,electric cells. a slide switch and a reflector. Firstly complete the circuit and then put two electric cells or batteries into the plastic case.when you close the switch the circuit will be complete and the bulb will glow. The reflector will pass the light too the big distance and and lighten the distance upto where the light the goes.
