In general, the converter with the fewest components and higher switching frequency will tend to have lower loss. If both converters have the same number of switching components and operate at the same switching frequency, their efficiencies will be comparable to each other.
How to get 3V from 5 volts?from learningaboutelectronics.com
So back to our circuit, if we have 5 volts and want 3V from it, we use the formula above. If we use a 10KΩ as our R 1 resistor, plugging in the values, we get R 2 = (V) (R 1 )/ (V IN - V)= (3V) (10KΩ)/ (5V - 3V)= 15KΩ. So we can use a 15KΩ resistor as our R 2 resistor with the R 1 resistor being 10KΩ.

How to calculate bleeder current?
Calculate the "bleeder current." The bleeder current is the current flowing in the voltage divider network, none of which flows through the load. The rule of thumb for designing a voltage divider is to make the bleeder current 10 percent of the load current. Our load current is 1 amp, therefore our bleeder current equals 0.1 amps. Calculate the total resistance for the voltage divider network. Total resistance equals the source voltage divided by the bleeder current. R total = E source/I bleeder = 12/0.1 = 120 ohms.
How to calculate current through a resistor?
Calculate the current flowing through R1. The current flowing through this resistor will be equal to the sum of the "bleeder current" plus the "load current." I R1 = I bleeder + I load = 0.1 + 1.0 = 1.1 amps. Calculate the resistance value of R1. R1 = 6/1.1 = 5.4545 ohms. In this case we would round down to 5 ohms, which would provide 5.995 volts to our load. That is close enough to the 6 volt rating of the load. Calculate the power rating for R1. P = 1.25 (1.1) (6) = 8.25 Watts. Use the next closest value, or 10 watts.
How do transformers work?
Transformers, which are often used to step-down voltage, work with AC (alternating current) voltages, not DC (direct current) voltages.
