When Ns>Np then transformer is:
Correct answer: A. Step up
- A. Step up
- B. Step down
- C. Primary
- D. Secondary
Explanation
When Ns>Np in a transformer, it is a step-up transformer.Here's what these variables represent:Ns is the number of turns in the secondary coil (the coil on the output side).Np is the number of turns in the primary coil (the coil on the input side).In a step-up transformer, the secondary coil has more turns than the primary coil. This configuration is designed to increase the voltage on the secondary side relative to the voltage on the primary side while reducing the current. Step-up transformers are commonly used in power transmission and distribution to increase voltage for long-distance transmission, which reduces energy losses due to lower current levels.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.

What happens to the flux if applied magnetic field is doubled on the same surface?
Whenever the magnetic flux linked with an electric circuit changes, an emf is induced in the circuit. This is called:
Faraday law states that the rate of change of magnetic flux is equal to:
