Thanks for taking the time to look at this post. I am new to the field but we all had to start at some point somewhere right.
I'm trying to study on my own and I came across this web pageand the very last question, just scroll all the way to the end and theres a 'challenge question', I don't know where im going wrong. My answers aren't the same as the answers given. Could someone instruct me on how to solve that very very primative cirucit.
Also could someone give me a practical example of why you need to know Ohms law, which i am studying on faith alone right now. Would it be something along the lines of "I have X component which runs on Y amps but I have 3Y amps running though, what resistance would i need" or something like that? Or am i way off.
Thanks for any help.
