(a) For use in a liquid crystal display, you want an electrode that is transparent to all visible light. You decide to use a doped semiconducting oxide with a mobility of 10-2 m2/V-s. What is the maximum conductivity you can expect from your oxide? Assume E = Eo
(b) You look at the sun through goggles that have been coated with a thin layer of highly-conductive metal such as silver. Briefly explain why and in which way the color of light will be altered.
Assume two cables have wire strands that are the same diameter and made of the same material. If one cable has 7 strands and another has 19 strands, which will have more resistance over a mile
A device moves 120 coulombs of charge from point a to b in 8 seconds. the distance between a and b is 6 cm. the energy expended in moving the charge is 600 Ws. calculate the voltage between a and b.
Find the charge on the capacitor in an LRC series circuit at t = 0.01 s when L = 0.05 h, R = 2 O, C = 0.01 f, E(t) = 0 V, q(0) = 5 C, and i(0) = 0 A. Determine the first time at which the charge on the capacitor is equal to zero.
A 60-Hz, single-phase transmission line has a length of 80 miles. Its shunt conductance (G) is 3.4×10?11 S/mile, resistance (R) is 0.1 ?/mile, capacitance (C) is 16 pF/mile, and inductance (L) is 0.56 mH/mile.
