Hi my grade 11 physics class is on its final unit (Electricity and Magnetism) and I am a little lost...... So far we are doing Charge and Voltage (we learned the formulas)... and we're expected to know that circuit diagram stuff and Ohm's Law? lol a bunch of stuff we were suppose to learn in grade nine... I was just wondering if you guys could provide me with a website or something which would help review some grade 9 electricity material or even some grade 11 stuff... I kind of don't understand the concepts (charge, voltage, current!!), I know it seems easy but I guess I didnt really learn it well in grade 9. I can do the math but I won't understand what it all means, lol. We are going to use what we learn and apply it to circuit analysis..........I just want a better understanding any help would be appreciated. thanks.
