Question

8.220V is changed to 2200V through a step up transformer.The current in the primary is 5A, what is the current in the secondary?


​

Answer 1

Answer:

It's simple just see step by step.

Explanation:

The transformers law is

V s /V p  = I p /I s

or, I s  = V p/V s x  I p

or, Is = 8.220/2200x 5 A

or, Is = 0.00374 x 5 A

So, Is = 0.0187 A

The current in the secondary is 0.0187 A .

Step-Up Transformer

A step-up transformer is a type of transformer that converts the low voltage (LV) and high current from the primary side of the transformer to the high voltage (HV) and low current value on the secondary side of the transformer. The reverse of this is known as a step down transformer.
