Lecture 3 Lecture 3 Phasors Lesson Objectives Apply the basic equations of voltage and current for the analysis of simple linear electrical circuits.
Resistance is the tendency of an element to prevent the passage of current through the element.
Inductance is the tendency of an element to store magnetic energy. In another sense it is the tendency of a device to resist changes in current. Capacitance is the tendency of an element to store electrical energy. In another sense it is the tendency of a device to resist changes in voltage. Transformer a device that converts electrical energy to magnetic energy to electrical energy.
