What is j 2 value?

It follows that j2 = −1. Using real numbers we cannot find the square root of a negative number, and so the quantity j is not real. We say it is imaginary. j is an imaginary number such that j2 = −1.

What is the value j?

The J value is defined as the elastic potential difference between the linear and nonlinear elastic bodies with the same geometric variables [52,53].

What is j in electrical engineering?

Electrical engineers use j for the square root of -1 while nearly everyone else uses i. The usual explanation is that EE's do this because they use i for current.

Why do engineers use j instead of i?

Special Symbols: i, j, and π

This is different than the way most mathematicians would write it: 3 + 7i. Engineers use j since i is reserved to mean current, and we place the symbol in front of the number rather than behind it.
