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:
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm
Explanation:
Hi, the ruler is in centimeters, from left to right each long line ( the ones with the number ) is a centimeter.
Since 10 millimeter equals 1 centimeter each short line is a millimeter (0.1 cm)
Knowing this, the measures of each block are.
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm
