1. A step-down transformer is used for recharging the batteries of portable devices. The turns ratio N2/N1 for a particular transformer used in a CD player is 3:43. When used with 120-V (rms) household service, the transformer draws an rms current of 170 mA. (a) Find the rms output voltage of the transformer. ? V (b) Find the power delivered to the CD player. ? W 2.What velocity would a proton need to circle Earth 1,285 km above the magnetic...
Problem1 In the concentric spherical conductors system shown in Figure 1, the inner conductor has positive charge-q and radius a. The outer conductor has radius b a) Using Gauss' Law determine the electric field vector E(r) in the region between the conductors (acrcb) and the potential difference Vab between them. b) Calculate E(r) and Vab if the two conductors have a 30 mm, b-40 mm, q 10uc, r-35 mm ε,-8.85x10-12C3(N.m2. For the circuit shown in Figure 2 find: a) the...
