What is the equivalent resistance between $A$ and $B$ in the given circuit?

Answer:

Solution:

AC and AD in series $= 2 Ω + 2 Ω = 4 Ω = A D$

ACD is parallel to AD

$∴$ $R = \frac{R_{1} R_{2}}{R_{1} + R_{2}} = \frac{4 \times 4}{4 + 4} = 2 Ω$

Similarly, AD is in series with DE

$∴$ $A E = 2 Ω$

$A E B = 4 Ω$ parallel with $A B = (8 Ω)$

$R = \frac{R_{1} R_{2}}{R_{1} + R_{2}} = \frac{4 \times 8}{8 + 4} = \frac{8}{3} Ω$
