Three resistors form a series parallel network. R1 is in series with a parallel combination of R2 and R3. R1 has a value of 1,000 ohms, R2 has a value of 1,500 ohms and R3 has a value of 2,200 ohms. What is the voltage dropped across each resistor?
12 volts DC is applied to the circuit

Without being given a voltage applied? I can only go by ratios.
Paralleled pair equivalent resistance = (1500 x 2200) / 1500 + 2200) = 891.9 ohms.
(1,000/891.9) = 1.12120 x the voltage across R1, as is across the paralleled pair. Both R2 and R3 have the same voltage across them.
If you have a voltage but omitted it, divide it bt 2.12120, and that will be the voltage across R2 and R3. The remainder is across R1.
