In his demo, Mr. Quan powered each of the 3 lights using a 1.5V battery. The resistance of the lights were measured and then added up. Adding up resistors like this demonstrated what principle? Group of answer choices Resistors in series have an equivalent resistance equal to the sum of the individual resistors. Higher resistance is needed for greater brightness Equivalent resistance in any circuit is always the sum of all the individual resistances
