Rank the brightness of the identical light bulbs in the circuit below. The brightness of a lightbulb is given by its power. P = I 2 R, and so brightness depends on current and resistance. If the bulbs are identical, they have the same resistance. They may not, however, experience the same current. Therefore, when you are asked to rank ...
Web1 Ω = 1 V/A (1.4). Ohm’s law holds for most materials and at common temperatures. At very low temperatures, resistance may drop to zero (superconductivity). At very high temperatures, the thermal motion of atoms in the material inhibits the flow of electrons, increasing the resistance.
