Question

Is the secondary to primary current ratio same as the secondary to primary voltage ratio in a transformer?

Answer 1

Dear Student,

● Answer -

No. The secondary to primary current ratio is reciprocal of the secondary to primary voltage ratio in a transformer.

◆ Explanation -

• The secondary to primary current ratio is equal to ratio of no of turns of the primary to secondary in a transformer.

Current transformer ratio = N(primary) / N(secondary)

• The secondary to primary voltage ratio is equal to ratio of no of turns of the secondary to primary in a transformer.

Voltage transformer ratio = N(secondary) / N(primary)

• Hence, relation between current transformation ratio and voltage transformation ratio is -

Current transformation ratio = 1 / voltage transformation ratio

Best luck dear...
