Question

Assume all batteries arc ideal (they have no internal resistance) and connecting wires have no resistance. Unlike most real bulbs, the resistances of the bulbs in the questions below do not change as the current through them changes. All the bulbs considered in thus problem are identical. What is true when one bulb is brighter than another? The current passing through the brighter bulb is smaller. There is not enough information to answer this question. The current passing through both bulbs are the same. The current passing through the brighter bulb is larger.

Explanation / Answer

We know that power is product of voltage and current.
thus we cant compare currents unless we have voltagesgiven.
Hence the answer would be second option. We can't tell with the given information.
