Question

For the following circuit, solve for R1, R2, R3, R4, and R5 given the specified voltages and current. The values of R will be 220, 330, 2200, 3300, or 10,000 ohms. Choose resistors that get you the lowest amount of deviation from the desired result. Remember that tolerance will be a factor in your calculations.

Explanation / Answer

For R1 :

(18-12.8) = (220+330+R1)* 1.336*10^-3 ; R1 = 3342 Ohm

For R2 :

12.8-11.5 = Req * I = 1.336*10^-3 * (R1*R2*R2/(R1R2+R2R3+R1R3))

So, 2200*2200*R2/(2200*2200+2200*R2+2200*R2) = 973

R2 = 8427.56 ohm

For R3:

Req = (11.5-8.1)/I = 2545 = R3 + (10000*330/(10000+330))

R3 = 2225.5 ohm

for R4 :

Req = (8.1-4.8)/I = (10000*R4/(10000+R4)) = 2470

R4 = 3280 ohm

For R5:

Req = 4.8/I = R5+3300

R5 = 292.8 ohm
