Key Points to Remember Three elements and two interconnection laws There are three physical elements in electrical systems: Inertia - characterized by INDUCTANCE (L) - opposes increase in current flow Dissipation - characterized by RESISTANCE (C, B) - eliminates current flow Elasticity - characterized by CAPACITANCE (C) - stores charge (potential energy) We use lumped elements that are ideal We usually deal with equivalent inductance, resistance and capacitance Inductance and capacitance are easiest to estimate Kirchhoff’s voltage law !" Newton’s 2 nd law Kirchhoff’s current law !" Kinematic compatibility © 2009 D. E. Adams ME 375 – Electrical Systems 5.2
Electrical Elements Inductance, resistance and capacitance (LINEAR) Each lumped (linear) element has its own characteristic q V R q V 1/C q V L Note that these are straight lines with constant slopes Capacitance is like the inverse of stiffness.
