The power dissipated by a light bulb’s resistor is proportional to how bright the light bulb glows. The lightbulb’s wattage is defined assuming it has a fixed resistance and is connected to a voltage source of 110 V. Two 110-V light bulbs, one “25 W” and the other “100 W”, are connected in series to a 110-V source. Which statement below is correct? The current in the 100-W bulb is greater than that in the 25-W bulb. The current in the 100-W bulb is less than that in the 25-W bulb. Each bulb will have a potential difference of 55 V. The 100-W bulb lights dimmer than the 25-W bulb none of the answers
