1 Determine an equation for the efficiency (power out/power in) of a four diode bridge AC rectifier circuit. Approximate the load as one large resistor and do not assume the diode resistance is negligible. Make sure to solve the equation so only known quantities (load resistance, source voltage, ect) and not unknown quantities (currents ect) appear in it. 2. Modify your equation to include a capacitor in parallel with the load that will smooth out the resultant DC voltage and...
