Astep-up transformer connected to a 110-v line is used to supply a hydrogen-gas discharge tube with 5.0 kv (rms). the tube dissipates 140 w of power. (a) what is the ratio of the number of turns in the secondary winding to the number of turns in the primary winding? (b) what are the rms currents in the primary and secondary windings? (c) what is the effective resistance seen by the 110-v source?

Why are graphs useful when interpreting data

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
