Answer to Question #134512 in Classical Mechanics for Fatima

Question

If 10 ampere current is flowing through primary coil and their transformation ratio is 20.Find the value of current flowing in secondary coil?

Answer 1

Solution

Current in primary coil(I_p) =10A

Transformation ratio (K) =20

Relationship between currents and transformation ratio is given by

$\frac{I_p}{I_s}=K$

Therefore

Current in secondary coil

$I_s=\frac{I_p}{K}=\frac{10}{20}=0.5A$

So current in secondary coil is 0.5A.
