Question

Seven) An ideal transformer has 25 turns on the input and 400 turns on the output. There is an input voltage of 120V and an input current of 0.200A.

a. What is the power input?

b. What is the power output?

c. What is the voltage output?

d. What is the current output?

e. Is this a “step up” transformer or a “step down” transformer?

Answer 1

(a)

The power input is

(b)

the power output is

(c)

(d)

and

(e)

here

hence it is step up transformer
