Current Electricity (R)
... Current is the flow of charge. Resistance is the hindrance to the flow of charge. Ohm’s Law = voltage to current ratio (V/I) = Resistance. Resistivity is an intrinsic property of a material that is proportional the the resistance. An increase in length of a conductor will increase resistance. An inc ...
