I believe your answer is:  

c=\frac{j}{u}; u\neq 0

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\boxed{\text{Solving for 'c'...}}}\\\\j = uc  \\------------\\\rightarrow \frac{j=uc}{u}\\\\\rightarrow \frac{j}{u}=c\\\\\rightarrow \boxed{c=\frac{j}{u}}}; u\neq 0

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
