Repeat (Problem) for a string consisting of 36 light bulbs.

Reference Problem

A string of 24 series light bulbs is connected to a 120-V supply as shown in Figure 5–71.

a. Solve for the current in the circuit.

b. Use the voltage divider rule to find the voltage across each light bulb.

c. Calculate the power dissipated by each bulb.

d. If a single light bulb were to become an open circuit, the entire string would stop working. To prevent this from occurring, each light bulb has a small metal strip which shorts the light bulb when the filament fails. If two bulbs in the string were to burn out, repeat Steps (a) through (c).

e. Based on your calculations of Step (d), what do you think would happen to the life expectancy of the remaining light bulbs if the two faulty bulbs were not replaced?
