How is the chemical energy contained in fossil fuels converted to electrical energy in an electric power station?
Fossil fuels are converted into chemical energy through an exothermic reaction called combustion, which produces heat—the more heat produced, the better the fuel. This heat is then used to boil water, and the resulting steam is used to turn a wheel that is attached to the axle of an electric generator, thereby producing electricity.

Fossil fuels are burned to produce heat, which converts water into steam. The steam drives turbines connected to generators, producing electrical energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- If a current of #4 A# passing through a circuit generates #12 W# of power, what is the resistance of the circuit?
- If a current of #3 A# passing through a circuit generates #90 W# of power, what is the resistance of the circuit?
- Why is current the same everywhere in a series circuit?
- An electric toy car with a mass of #4 kg# is powered by a motor with a voltage of #7 V# and a current supply of #9 A#. How long will it take for the toy car to accelerate from rest to #7/2 m/s#?
