How does electricity come from candle?

Answer 1

I can think of three ways whereby a candle could produce electricity:

1). Heat water with the flame. When the water boils, use the steam to spin

a turbine mounted to an electrical generator.

2). Place the flame close by a photovoltaic cell, which can convert a part of

the candle's heat and light to electrical energy.

3). Place a pinwheel behind the candle flame, attached to an electrical generator,

and wait for someone to come along and blow out the flame.

Answer 2

Electricity cannot directly come from a candle. Candles produce heat and light through combustion of wax and a wick. To generate electricity requires a different process, such as using a power plant to convert the energy stored in fuels like coal or natural gas into electrical energy.
