Formulas for calculations can be difficult to use at times. The check
values presented here for various types of electrical calculations can provide a way to verify
that the formulas are being used correctly. Here's how they can work for you:
Select a calculations type that you want to master.
See the set of check values on this website. Click the link on this page
below to go to the formulas you need to master.
Use the formulas for these values to verify that you are entering the values
correctly to arrive at the check value given.
So if you are checking the formula for Ohms Watts to find E when you know I
and R, enter I then times then enter R.
Now press the equals button just as the formula states. You should get the same
answer as in the check values. If you do, then you have entered the values correctly
and can have confidence that any problem can correctly be solved when using that
Then go on to do the same for every formula on the list of
formulas. In that way, if you are entering anything incorrectly, your answer
will not match the check value. Then you can determine where you went wrong,
never to make that same mistake again. Hopefully.
You can return from time to time to verify that you still have the touch.

types of problems.
