For example, if I attach a solenoid with a small cylindrical magnet going through it and attach it to a galvanometer, the needle of the glavanometer moves to a particular side depending on the conditions. Current is generated, that explains why the needle moves to a particular side. Now my...
I know that current is generated by charges moving in an electric field caused by other nearby charges is this phenomenon called Ohm's Law? I'm a bit confused.
I know that according to Ohm's Law that the voltage is directly proportional to the current in a resistor. Upon examing my graph that I have calculated in class, a resistor follows Ohm's Law because the slope was a straight line. The part I am confused about is why would the slope be equal to...
