1986B3. In the circuit shown above, X,Y. and Z represent three light bulbs, each rated at 60 watts, 120 volts. Assume that the resistances of the bulbs are constant and do not depend on the current.
a. What is the resistance of each bulb?
b. What is the equivalent resistance of the three light bulbs when arranged as shown?
c. What is the total power dissipation of this combination when connected to a 120 -volt source as shown?
d. What is the current in bulb X?
e. What is the potential difference across bulb X?
f. What is the potential difference across bulb Zd ?
