Hi,
I was going through the script which was done 10 years back. In that i found one formula as mentioned below. This formula is used to calculate the Total output power. Bit wondering from where this formula is came from. please tell me if anyone have idea about the below formula,

(V*V/1.40)+(VI/0.02)

Thanks,
Kalpana

What script?
Total output power of what?
How do you think we can give you an answer from such meager data?

The formula for power in a resistor is V^2/R, which is similar to the first term in that formula, but that may be deceptive. What the second term is, is anybody's guess.

The second term starts with I x E, so it is a measure of power, too.
If the rational number on the left is equal to some resistance, and the rational number on the right is merely a constant.
Then it would be a formula for power.
and that's what the TS said.
