Circuits and light bulb brightness
WebThe 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 … WebAs the voltage goes higher so does the brightness of light in the blub. B. How does changing the battery’s voltage affect the brightness of the light. ... Then add two more light bulbs to the circuit, parallel to the first two. A. How does each new light bulb affect the others? There is no effect on the new light bulbs. B.
