Which of the following would offer the least resistance to a a short, thick copper wire (b) a short, thin copper wire (c) a long thick copper wire (d) a heated copper wire (e) a long, thin rubber tub a bird if it touches both wires at once. this is because when the bird touches both wires 23 is safe as long as it perches on a single electrical wire, but risks electrocution (a) twice as much current passes through it (b) twice as much voltage passes through it (c) it has half as much resistance (d) it has a potential difference across which of the following takes place in an ac circuit? (choose as many as apply.) (a) electrons move through forward very slowly. (c) electrons vibrate back and forth in place with no appreciable movement. (d) a pulsating electric field travels through the circuit at nearly the speed of light. a circuit at nearly the speed of light. (b) electrons drift superconducting materials do not obey ohm's law; when current flows through a superconductor, there is no voltage drop across the superconductor. what is the electrical power output when a current flows through a superconductor? (a) at least 100 watts (b) an infinite amount of power, which is why no current can be sent through a superconductor (c) there is no power output (d) the number of watts of 25 wer output equals the number of amperes in the current (e) there is not enough information given to answer this question. lowing questions in the space provided. if you wish, you may draw and label an our answers. where indicated, you must show your calculations to answers. to aid in giving ceive full credit for a correct answer. re electron is -1.6 x 101°c. what is the force exerted between be sure to note whether the force is attractive or two electrons separated by one meter? ( show your calculations.

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
