Answer:
Due to power factor correction; voltage regulation is improved and efficiency is increased.
Explanation:
Power Factor Vs Voltage Regulation:
When the power factor is improved, the current in the system decreases as power factor and current have inverse relation.
When current decreases, the corresponding voltage drops in the system decreases as the voltage and current are directly proportional.
Since the voltage drop decreases, the voltage regulation improves since the voltage regulation is given by
Voltage regulation = (Vin - Vout)/Vout x 100%
Vout will be greater due to less voltage drop.
Power Factor Vs Efficiency:
Efficiency is given by
η = Pout/Pin
but Pin = Pout + Plosses
η = Pout/Pout + Plosses
When power factor is improved, the current decreases, the decrease in current reduces the power losses since the losses are directly proportional to the square of current (I²R) therefore, decrease in Plosses results in the increased efficiency of the system.
Answer: observational error
Explanation:
Answer:
150 W
Explanation:
Power is energy per unit time. The power generated by the engine is ...
(3000 J)/(20 s) = 150 J/s = 150 W
The engine generated 150 watts.
Answer:
Distribution (or its more sophisticated counterpart, supply chain management) can add value to goods and services by making them more easily and conveniently available to consumers. ... This means that you need good wholesalers and good transportation systems to get your products to the retailers.

A continuous time-varying 1-D signal is sampled by narrow sampling pulses at a regular rate fr = 1/T, which must be at least twice the bandwidth of the signal. At first, it may be somewhat surprising that the original waveform can be reconstructed exactly from a set of discrete samples.
