The turns ratio N2/N for a particular transformer used in a DVD player is 1:12. When used with 120-V (rms) household service, the transformer draws an rms current of 50.0 mA from the house outlet. (a) Find the rms output voltage (in V) of the transformer. (b) Find the power (in W) delivered to the DVD player. W (c) What If? What would be the current (in mA) drawn from the house outlet if the transformer had an efficiency of 88.0%, but the power delivered to the Blu-ray player remains the same? mA Need Help?
