The circuit in Figure P19.34 shows three identical lightbulbs attached to an ideal battery with ε = 18 V. If the resistance of each bulb is 200 Ω, what are (a) the current through bulb 1 and (b) the current through bulb 2? (c) If bulb 2 burns out, what happens to the brightness of bulbs 1 and 3?

(i) The brightness of both bulbs stays the same.

(ii) Bulbs 1 and 3 get brighter.

(iii) Bulbs 1 and 3 both get dimmer.

(iv) Bulb 1 gets dimmer while bulb 3 gets brighter.

(v) Bulb 1 gets brighter while bulb 3 gets dimmer.

Hint: The brightness of a bulb increases as its current increases.
