Question

The transformation ratio in the step-up transformer is ______

विकल्प

• one.

• greater than one.

• less than one.

• the ratio greater or less than one depends on the other factors.

Answer 1

The transformation ratio in the step-up transformer is greater than one.

Explanation:

Transformation ratio k = `"N"_"s"/"N"_"p" = "V"_"s"/"V"_"p"`

For step-up transformers, N_s > N_p i.e., V_s > V_p, hence k > 1.
