Work and time because the power depends on how much it can do in so much time
Answer:
W = - 184.8 kW
Explanation:
Given data:
We know that work is done as
for
density of air is 1.22 kg/m^3 and
for
W = -[14 + 1.708[400-300]]
W = - 184.8 kW
This allows. the defogger to shut down after a predetermined length of time the defogger to function just until the rear window is clear the defogger to be independent of the ignition switch none of the above.
Answer:
a. 30.O7A
b. no reading
Explanation:
for the first load with power factor 0.8, we calculate the reactive power
note the reactive power is calculated as
where p=power
a. for the first load the reactive power is
for the second load the reactive power is
The total reactive power is the summation of both reactive power in he load
and the total real power is 25kw
Hence using Pythagoras theorem to calculate the apparent power we have
Hence we can determine the source current using
b. in a balance 3phase system, there is no neutral current, Hence the ammeter will read zero current
Answer:
2000-7000 * 6% = - 0,000126
