You have four light bulbs, light bulbs one, two, three, and four. All have the same intensity. Bulb one is unscrewed causing only bulb one to go out. Now, bulb two's intensity is 30% greater than it was originally. Bulbs three and four each have 2/3 of their original intensity. Based upon this information, how are the four bulbs wired?3 AnswersPhysics1 decade ago
