Electrostatic Potential And Capacitance

Question

Wired Faculty App

The number of turns in secondary coil of a transformer is 100 times the number of turns in the primary coil. What is the transformation ratio?

Solution

Given, number of turns in secondary coil of transformer is 100 times the number of turns in the primary coil.

Transformation ratio is given by,

\Rightarrow

k = \frac{N_{s}}{N_{p}}

Since,

Ns = 100 \times N_{p}

Thus,

k = \frac{100 N_{p}}{N_{p}} = 100 .
