Hi folks... I am just starting out in electronics and am taking a home study course. The subject material provided is questionable and confusing by times. I tried calling a course advisor, who obviously was reading out of a prescripted manual and by the time I finished, I was worse off. Anyway, could someone please help me with the following including a step by step solving process. Q: what is the maximum current recommendation for a 1200-ohm, 1/4-watt resistor that is designed to work at 100% of its rating...using the formula I = (square root of) P/R?
