P HYSICS 1302, F ALL 2007 , P ROF . J. M ILLER , I NSTRUCTOR Introductory Physics, 2 nd Semester Formula Sheet for Exam #1 e = 1.6 x 10 -19 C, ε 0 = 8.85 x 10 -12 C 2 /(N·m 2 ), k = 1/4 π 0 = 8.99 x 10 9 N·m 2 /C 2 , μ 0 = 4 π x 10 -7 T·m /A Coulomb’s law: F = k | q 1 || q 2 | / r 2 ; Electric field due to a point charge: E = k | q | / r 2 Electric flux: Φ = Σ E Δ A cos θ ; Gauss’s law: Φ closed surface = q enclosed / 0 . Potential energy vs. electric potential: Δ U = q Δ V . Relation to electric field in direction of displacement Δ s : E = - Δ V / Δ s . Electric potential due to a point charge (relative to potential as r ): V = kq / r . Displacement charge across a capacitor: Q = CV . Capacitance of parallel plate capacitor: C = κε 0 A / d ( κ = 1 for air or vacuum). Energy stored in a capacitor: U = ½ QV = ½ CV 2 = Q 2 / 2 C . Energy density of an electric field: u E = ½ 0 E 2 . Electric current:
