We can define power as the rate of doing work, and it is the amount of energy consumed per unit of time. Formula of Power As discussed, power is the rate of doing work. Therefore, it can be calculated by dividing work done by time. The formula for power is given below. \(\begin{...
This low power factor increases the current, which results in an increase in losses and causes a decrease in the efficiency of the system. Hence, it is necessary to improve the power factor of the system, in order to ensure economic transmission and distribution of electric power. This ...
