Question:

In the circuit of Fig, each resistor represents a light bulb. Let R1 = R2 = R3 = R4 = 4.50Ω and E = 9.00V. (a) Find the current in each bulb. (b) Find the power dissipated in each bulb. Which bulb or bulbs glow the brightest? (c) Bulb R4 is now removed from the circuit, leaving a break in the wire at its position. Now what is the current in each of the remaining bulbs R1 R2, and R3? (d) With bulb R4 removed, what is the power dissipated in each of the remaining bulbs?
(e) Which light bulb(s) glow brighter as a result of removing R4? Which bulb(s) glow less brightly? Discuss why there are different effects on different bulbs.
