Always searching for an answer to my why’s, never satisfied and longing to know more. You know, I used to be terrible at maths when I was in elementary school. My teacher was aware of my potential and just wouldn’t let me… Read more My First Blog Post

Lightbulbs consume a certain amount of power, according to the formula P=VI

Voltage and current | What are they?

Voltage and current are two very important quantities that we want to monitor in circuits to exactly know what’s going on. But what are they, and what is the difference… Read more Voltage and current | What are they?

i-th root of i

In my previous post we talked about i^i and we evaluated it. We found that the result is a real number, although you would expect it to be complex since i is an imaginary number. Is this the case for the i-th root of i? First of all, let’s write this as a power: Now, this is can also be written as We already know what i^i equals therefore, This means it’s simply the inverse of i^i, and so it’s a real number as well! If you use a calculator… Read more i-th root of i
