Hello everyone.

<krom>

To convert VA to I (Amperes), let's take the following example:

You have a transformer with a primary of 220V and a secondary of 12V, for a total power of 2VA.

- You divide the VA (2VA) by the voltage of your secondary (12V)
(2VA/12V) = 0.17A

Another one:

You have a transformer with a primary of 220V and two secondaries of 18V, for a total power of 160VA.

- You divide the VA by two since you have two secondaries!
(160VA/2) = 80VA
- Then you divide the VA (80VA) by the voltage of your secondary (18V)
(80VA/18V) = 4.44A on each of your secondaries.

It's simple, right!?
