Question

A four-resistor circuit is shown in the figure. The values of the resistors are as follows: R1=4 Ohms, R2=R3=R4-3 Ohms. What is the equivalent resistance Reg for this circuit? RA R R₂ 3 R₃ O 0.8 ohms 133 ohms 3.5 ohms 25 ohms 0.67 ohms

Answer 1

gwen, resistor wint RD where R = 42 Rq = Rg = R₂ = 32 [2=chm R. Z R by R sit. R R, { Rz + I 1 Ra - Since RG & Rg are in series, they can be replaced R' sit. R' = RG + Rs. Teme the winnt becomes if there are n-resistors i (R., R2, ....Rp is series Equivalent resistance Req, is Rega Rit Ratio.tk The equivalent resistance of this writis, 1/ Req Ri R ㅗ ㅗ t It tás Req 4 3+h+2 9 4 Req=2 = 1.338 if there are n resistors LR, R2 ...Rp in poorallel.connection, Equivabnt resistance is quen by Reg R R Rn DE 2 + 1 / 3 3 3+3 - 32 12 12 + 1 + +

SUMMARY:

The equivalent resistance of the 4-resistor circuit given is 1.33 Ohms
