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