An LM317 is connected between two decoupling capacitors. There is a 220ohm resistor between the output pin and the adjust pin. Note the voltage drop between the output and adjust pins is 1.25V. Find the resistor needed between the Adjust pin and ground to ensure 5 V is dropped across the load. Enter your answer in ohms: _ohms

A three phase full wave rectifier is shown below along with peak phase voltage Vm-169.7V. The load is purely resistive. The rectifier delivers Ipc = 100 A and the source frequency is 60 Hz.
