Question

What is the value of x if one coulomb is equal to x emu?

Answer 1

Step 1 : Units:

1. The electromagnetic unit (emu) of charge is the derived physical unit of electric charge in CGS - emu system.
2. Coulomb is the SI unit of electric charge. It is defined as the charge transported by 1 ampere current in one second.

Step 2 : Conversion :

We have given that $1C=x$

We know that $1C=\frac{1}{10}emu$

so, $x=\frac{1}{10}emu$.

Hence, value of x is $\frac{1}{x}$
