The voltage across the secondary winding is 10,000 V, and the voltage across the primary winding is 25,000 V. If the primary win

Allisa [31]

Answer

80 coils

Explanation

The turn rule of a transformer says that, the amount of voltage induced in the secondary coil is proportional to the number of coil. It is simplified by the ratio:

Np/Ns = Vp/Vs

200/Ns = 25,000/10,000

200 × 10,000 = 25,000Ns

2,000,000 = 25000Ns

Dividing both sides by 25,000,

Ns = 2,000,000/25,000

= 80 coils

How does a mirage occur in a deser?explain with a labelled diagram.

Ronch [10]

Answer:

Mirages happen when the ground is very hot and the air is cool.

Explanation:

They happen when light passes through two layers of air with different temperatures. The desert sun heats the sand, which in turn heats the air just above it. The hot air bends light rays and reflects the sky.

When you see it from a distance, the different air masses colliding with each other act as a mirror.
