Question

A four-resistor circuit is shown in the figure. The values of the resistors are as follows: R₁=8 Ohms, R₂=R₃=R₄=4 Ohms. What is the equivalent resistance Req for this circuit?

R4 w m R1 R2 R3 -

a) 0.67 ohms

b) 1.5 ohms

c) 2.0 ohms

d) 2.5 ohms

e) 4.0 ohms

Answer 1

Ra RI 3R2 equivalent seesistance of serviescombination of R3 and Rais, Rs RotRA -> Rs (4+4), = Rs=84 Hence equivalent wian't is RE &n, R2 = R3 = R4 = 42 drawn os Rs R R2 Reeq equivalent resistance of parallel combination of Ri, R2 and Rs is, 1 kisha Req Hara 2 =) Req= 1 colle cop 8 4 > Rea 2 => Req sore 4 1 1+ 2+1 8 Req=an circuit is an Equivalent resistance of :option © , i.e. an is the correct answer '.
