der serop10 18 shown in the figure below. (Assume Ri 12.0 n, Ra 3.40 n, and V- 7.70 V.) Responses/submit?dep 15871049aQ23 Bell Biv Devoe When' webstudent/Assignment p.000 40 net X a webassign the drcuit 400 n 500 n (a) Calculate the equivalent resistance of the Ri and 5.00-n resistors connected in parallel. (b) using the result of part (a), calculate combined resistance of the R s.00 n and 4.00-n resistors. the (c) calculate the equivalent resistance of resistance found in part (b) and the parallel 3.00-n resistor. the combined a) Combine the equivalent resistance found in part (c) with the Ri resstor Salou the total current in the croul.

Explanation / Answer

a) R1 and 5.0 ohms are connented in parallel

Rp = [1/12 + 1/5]-1= 3.53 ohms

b) Rp and 4.0 resistor in series

Rs = 3.53 + 4 = 7.53 ohms

c) Rs and 3.0 ohms are in parallel

Rp1 = [1/7.53 + 1/3]-1= 2.15 ohms

d) 2.15 ohms and R2 are in series

= 2.15 + 3.40 = 5.55 ohms

e) I = 7.7 / 5.55 = 1.39 ohms
