Lecture 14 EE135, Midterm#2 Thursday, February 28 Will cover: Chapters 3-5 Homework # 3-5 EE 135 Midterm #2 Be able to calculate Electrostatic and Magnetic Fields from any charge or current distribution (ie, know how to use Coulomb’s Law. Gauss’ Law, the Image Method, Biot-Savart Law, Ampere’s Law ) The charge continuity equation (div J = -dρ/dt) Be able to calculate capacitance, resistance, conductance, inductance from different geometrical elements Be able to calculate E, D, B, H across boundaries of different permittivity and permeability Forces on charged particles, stationary and moving Torque on wire loops in magnetic fields EE 135 Midterm #2 Material Know how to use all four of Maxwell’s equations and what they mean Be able to use all the tools of vector calculus And understand the “curl”, “gradient” and “divergence” Electromagnetic scalar and vector potentials (V and A ) Constitutive properties of materials Relations between E and D, H and B in material Maxwell’s Equa:ons Coulomb’s Law Electric field at point P due to single charge Electric force on a test charge placed at P Electric flux density D Gauss’s Law Application of the divergence theorem gives: Biot‐Savart Law Magnetic field induced by a differential current: For the entire length: Ampère’s Law (sta:c case) Note: I is the current enclosed by the line contour Vector Analysis Electrostatics Electrostatics Boundary Condi:ons Electrostatics Electrostatics Electrostatics Electrostatics Electrostatics Magnetostatics 4 ohms Not 4 W Magnetostatics Vector potential from a current distributed over some volume R EE 135 Midterm #2 Be able to calculate Electrostatic and Magnetic Fields from any charge or current distribution (ie, know how to use Coulomb’s Law.
