Most loads in modern electrical distribution network are inductive and resistive loads. Resistive loads are loads that convert all form of energy to heat and they always have heating element incorporated in there design. Examples include: Incandescent bulb, heater, cooker etc. Resistive Load: Resistive loads require one type of current - - Working power (kW) which is used to perform the actual work of creating heat, light etc Inductive Load: Inductive loads are loads that operate base on the principle of electromagnetic induction. They always have coils in them. Example includes: Transformers, electric motor, fan etc. When a current is supplied to an inductive load. It converts this current to magnetic using the coil inside it. Because it is an inductive load, current lags voltage by an angle of 90 degree. Inductive load requires two kinds of current: - Working power (kW) to perform useful and actual work of creating heat, motion, machine output etc - Reactive power (k...
