Unformatted text preview: Chapt. 26 Capacitors and Capacitance Multiple-Choice Problems 026 qmult 00100 1 1 5 easy deducto-memory: capacitor defined 1. “Let’s play Jeopardy ! For $100, the answer is: An electrical device consisting of two conducting elements (called plates) separated by vacuum or a dielectric. The plates carry equal and opposite charges. The device is used to store electrical potential energy and charge.” What is a/an , Alex? a) resistor b) inductor c) transistor d) and-gate e) condenser—no, no a capacitor 026 qmult 00200 1 1 3 easy memory: capacitance geometry 2. The capacitance of a capacitor ideally depends only on: a) its dielectric environment. b) its geometry. c) its geometry and its dielectric environment. d) the potential put on the capacitor. e) the charge put on the capacitor. 026 qmult 00300 1 1 4 easy memory: C=Q/V 3. The standard formula for capacitance with standard symbols is: a) C = V/Q . b) C = V 2 /Q . c) C = Q 2 /V . d) C = Q/V . e) C = Q − V ....
