Unlike most real bulbs, the resistances of the bulbs in the questions below do not change as the current through them changes. All bulbs considered in this problem are identical. Assume all batteries are ideal (they have no internal resistance) and connecting wires have no resistance.
1. The current passing through the brighter
bulb is larger.
2. Not enough information is given.
3. The current passing through the brighter
bulb is smaller.
4. The current passing through both bulbs
are the same.
