You have a low voltage lighting system that requires a 24 V RMS source, but all that is available is the 120 V RMS outlet on the wall (frequency of 60 Hz). If you make a transformer with the primary coils hooked up to the source voltage and the secondary coils hooked up to the lighting system, how many coils would you design the primary and secondary coils of the transformer to have? How would the power dissipated...

You need to design a DC power supply that provides an average DC output voltage of 5V to charge your cellphone. The maximum allowed ripple at the output is ±200 mV. Your cellphone can be modeled as a 1 50Ω load. You have to use a bridge rectifier with four diodes. Note: For calculations, consider constant voltage drop model of the diode with V0 = 0.7V. (a) The charger is designed to use in the US, i.e. transformer primary is...
