For two reasons:
1- because these roads generally follow the path of least effort: if there is a big boulder or a particularly steep embankment, the roads are build to wind around these difficult sections, avoiding them.
2- Because the hills can be climbed gradually. If a path goes straight up the side of the mountain, this path will be very steep. If the path goes across the side of the mountain, climbing gradually, then it will be easier to climb. This will probably take longer but the alternative, a hill climbing straight up the side of the mountain, is dangerous for any car/bike/animal-pulled cart that doesn't have enough power to prevent them from slipping down and causing an accident. This is particularly true for animal pulled carts, which have less power and so there is a greater risk that the horse/donkey/person/cargo will slipping down the mountain.

How the input voltage is changed to an output voltage in a transformer?
Transformers work on the induction principal of the flux of the primary winding cutting the wires of the secondary winding. The amount of turns in the primary in relationship to the amount of turns in the secondary is the transformers winding ratio. This ratio is what governs the voltage value of the secondary winding.

Why are winding roads built on mountain?
If a road were to go straight up a mountain, its rise angle would be much too steep for cars to handle. By making the roads winding, you can make the rise angle much lower on each section of the road, making it much safer and easier to navigate.
