Consider a circuit containing five identical light bulbs and an ideal battery
A. Consider a circuit containing five identical light bulbs and an ideal battery. Assume that the resistance of each light bulb remains constant. Rank the bulbs (A through E) based on their brightness.Rank from brightest to dimmest. To rank items as equivalent, overlap them.B. What happens to bulb C?It gets dimmer.It gets brighter.There is no change.
