It is only important if you want to be good at whatever it is you do in the electrical industry.
Understanding the relationship of Voltage, Current, and resistance will make you better at understanding some of the code rules, why certain connections are made the way they are, being a better 'trouble shooter', ETC...
and then when you learn this, you can pass it along to another.
There are some very good mechanics out there, and then there are the exceptional ones who can not only build it, but know why!!
Good Luck and always keep learning,

P.S. I read these forums, because there are some very talented people here who are more than willing to help.
