Four resistors, R, = 12 0, R2 = 15 N, R3 = series combination of R, and R2 is connected in parallel with the series combination of R3 and R4. The combination is then connected across a 12 V DC power supply. 10 N and R4 80 are connected such that the %3D %3D A. Draw the schematic diagram and label the circuit elements. B.
