(a) Calculate the equivalent resistance of the R1 and 5.00 Ù resistors connected in parallel.
1 Ù

(b) Using the result of part (a), calculate the combined resistance of the R1, 5.00 Ù, and 4.00 Ù resistors.
2 Ù

(c) Calculate the equivalent resistance of the combined resistance found in part (b) and the parallel 3.00 Ù resistor.
3 Ù

(d) Combine the equivalent resistance found in part (c) with the R2 resistor.
