Question

The primary coil of a transformer has 221,792 loops. The secondary coil has 1,812 loops. The primary coil has a 78 A current and 54 V.

a.) Is this a step-up or step-down transformer? How do you know? Choose one of the following.

_____ It is a step-up transformer because the primary current is greater than the primary voltage.
_____ It is a step-down transformer because the primary has more loops than the secondary.
_____ It is a step-up transformer because the primary has more loops than the secondary.
______ It is a step-down transformer because all transformers are step-down transformers.
______ It is a step-down transformer because the primary current is greater than the primary voltage.
______ It is a step-up transformer because all transformers are step-up transformers.


b.) Determine the power of the primary coil.

ANSWER:_____ W

c.) Assuming no losses, determine the power of the secondary coil.

ANSWER:_____ W

d.) Calculate the voltage in the secondary coil.

ANSWER: _______ V

e.) Calculate the current in the secondary coil.

ANSWER:______ A

Explanation / Answer

please check the answers once again ..those are correct as , I got power in primary coil is approximately equal to power in secondary coil..(this is a check) the order of answers are a) then c) then d) and then b)
