Question

Eight resistances each of resistance 5Ω are connected in the circuit as shown in figure. The equivalent resistance between A and B is –

• A. $\frac{8}{3}\Omega$
• B. $\frac{16}{3}\Omega$
• C. $\frac{15}{7}\Omega$
• D. $\frac{19}{2}\Omega$

Answer 1

Answer: (A)

$\frac{8}{3}\Omega$

Answer 2

The given circuit can be redrawn as

∴ R_AB = $\frac{8}{3}\Omega$
