Answer:
full load current = 7.891151 A
so correct option is b. Ir= 7.89
Explanation:
given data
Energy E = V = 240 V
frequency = 60 Hz
full-load slip = 0.02
full-load speed = 1764 rpm
winding resistance = 0.6 Ω
winding reactance = 5 Ω
to find out
rotor current at full-load
solution
we will apply here full load current formula that is express as
full load current =
...................1
here S is full-load slip and E is energy given and R is winding resistance and X is winding reactance
put here value we get
full load current =
full load current = 7.891151 A
so correct option is b. Ir= 7.89

Yea, ‘Who wants to fight with me’
Answer: Yes, it will be around 40ppm(at steady state)
Explanation:
The above question can be solved by performing material balance of CO in the building. The material balance equation is given by, Rate of change of CO in the building = Rate of inflow of CO into the building - Rate of outflow of CO from the blood
