CHAPTER FORMULAS & NOTES. Page 5. 5. Wattless Current. The component of current differing in phase by π/2 relative to the voltage is called wattles current.
It is current whose magnitude changes with time and direction reverses periodically. I=I0sin t where I0 is the peak value of a.c. and =2п/T is the frequency.
The following formula gives the alternating current. I = I0 sin ωt. I = I0 sin (2π/T) t where I0 is the peak value of Alternating Current (AC) Angular
