Find the total current throught the circuit; and find current through R0; and voltage drop across R4; and find current flowing through R1. First find the equivalent resistance of the shunt resistors (by using 1/R=1/R1+1/R2+1/R3). Then add this with R0 to find total series resistance. Again using above find total combined resistance along with the parallel resistor. Using Ohm's law and the totall resistor find total current. Then using the right variant of Ohm's law (V=IR) find the current through the required resistors and its voltages.
