To determine the current in each armature conductor, we need to calculate the total load current and divide it by the total number of armature conductors.
Given:
Number of lamps = 50
Power of each lamp = 60 W
Voltage of each lamp = 120 V
Armature resistance = 0.2 Ω
Total load power = Number of lamps × Power of each lamp = 50 × 60 W = 3000 W
Total load current = Total load power / Voltage = 3000 W / 120 V = 25 A
Since it is a 4-pole generator, there are 4 sets of armature conductors.
Number of armature conductors per set = Total number of armature conductors / Number of poles = (4 × Number of conductors per pole) / Number of poles
Since it is a wave winding, the number of conductors per pole is equal to the total number of conductors divided by the number of poles:
Number of conductors per pole = Total number of conductors / Number of poles = 50 / 4 = 12.5
Since the number of conductors must be a whole number, we can consider 12 conductors per pole.
Number of armature conductors per set = (4 × 12) / 4 = 12
Now we can calculate the current in each armature conductor:
Current in each armature conductor = Total load current / Number of armature conductors per set = 25 A / 12 = 2.083 A
Therefore, the current in each armature conductor is approximately 2.083 A.
