    A step-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 75 W of power.

    1. What is the ratio of the number of turns in the secondary winding to the number of turns in the primary winding?
    2. What are the rms currents in the primary and secondary windings?
    3. What is the effective resistance seen by the 110-V source?
