Question

when a transformer have secondary turn to primary turn ratio is 1 then the transformer is

step up
step down
neither step up nor down
n.o.t​

Answer 1

If the secondary voltage is less than the primary voltage, the transformer is known as a STEP-DOWN transformer. If the secondary voltage is greater than the primary voltage it is known as a STEP-UP transformer.

Hence, in a step-up transformer, the number of turns in the primary is less than the number turns in the secondary
