Question

Some questions to solve : (1) Why AC is preferred over DC. (2) How AC power is expressed as DC power in case when AC voltage is applied across resistor. (3) What is phasor diagram ? (4) How inductive reactance changes when the value of L decreases. (5) What are the values of Inductive reactance and capacitive reactance in case DC is applied. (6) Show that power dissipated in purely inductive or capacitive circuit is zero. (7) State phase relationships between current and voltage in cases of resistive,inductive and capacitive circuits.
