A.C Fundamentals, Circuits And Circuit Theory Set 1

The current through each element is same The voltage across element is in proportion to it's resistance value The equivalent resistance is greater than any one of the resistors The current through any one element is less than the source current

Apparent power is more than actual power Reactive power is more than apparent power Actual power is more than reactive power Reactive power is more than actual power

Changes in the stored energy in the inductors and capacitors Impedance of the circuit Applied voltage to the circuit Resistance of the circuit

Increasing core length Decreasing the number of turns Decreasing the diameter of the former Choosing core material having high relative permeability

R/Z Cosine of phase angle difference between current and voltage Ratio of useful current to total current Iw/I All above
