Question

What is the equivalent resistance between $A$ and $B$?

• A. $0.0\Omega$
• B. $6.0\Omega$
• C. $16\Omega$
• D. $48\Omega$

Answer 1

The correct option is C $16\Omega$

Equivalent resistance of the resistances connected in parallel $\frac{1}{R_p}=\frac{1}{12}+\frac{1}{12}+\frac{1}{12}$

$⟹$ $R_p=4$ ohms

Now equivalent resistance between A and B $R_{AB}=3+9+R_p$

$⟹$ $R_{AB}=3+9+4=16$ ohms
