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.
