Question

which Transformer turning wire in the secondary coil is less than that of primary coil


​

Answer 1

Explanation:

step down transformer

If the number of turns on the secondary coil is less than the number on the primary coil, then the output voltage will be smaller than the input voltage. We call this type of transformer a step down transformer. We use a step down transformer to step the voltage down from a high voltage to a low voltage.

Answer 2

Answer:

The transformer operates on a maximum flux density of about 1.8 wb/sq.meter.

In a step-up transformer, the primary voltage is less than the secondary. So, to keep the flux density at the maximum value(1.8 wb/sq.m) the less number of turns are required. The ratio of primary voltage and number of turns is equal to the flux in the transformer.
