A combination of resistors is shown below. The equivalent resistance between the terminals P and Q is:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $\frac{11}{4}Ω$
$\frac{1}{R_2}=1+\frac{1}{3}=\frac{4}{3}$
$⇒R_2=\frac{3}{4}$
$R_{net}=1+1+\frac{3}{4}=\frac{11}{4}Ω$
