Let's say a AA battery (1.5V) is hooked up to a simple circuit to power up a bulb (I want to assume the bulb lights up). If I switch out the AA battery for a D size battery (1.5 V), the light bulb will be brighter. Because the V is the same, I assume the current went up. Ohms law says V=IR therefore R=V/I so if I goes up, then the resistance goes down. I see resistance as the hindrance of the flow of charge. It is confusing to me that the increase in current will mean a decrease in the hindrance of the flow of charge. Can someone point out the where I am going wrong - or maybe provide me with a better definition of resistance? Thanks!
