i have taken the master electrician test twice and both times i have missed by 2 incorrect answers. i feel like my areas to improve on are the demand factors and motor calculations. im going to try to retest asap while some of the questions are still fresh at memory. where might i get some sample practice calculations that could explain these better. one of the questions that i had incorrect was what is a resistor with with a single orange stripe? what part of the code might this be related to. thanks for any help you may be able to provide.
