Question

in a transformer there are 500 turns in primary and
2000 turns in secondary
primary voltage is 120v and primary current is 0.1 A find thw voltage current and power in secondary​

Answer 1

Answer:

First we use the fact that the ratio of the voltage on the secondary and on the primary will be the same as the ratio of the number of turns of both coils,

⇒u=u1u2=N1N2

We evaluate the unkown secondary voltage -

⇒u2=N1N2u1

We substitute the given values -

⇒u2=50010×120v=2.4v

Hence, the answer is 2.4v.
