Equivalent Circuit Solution

Equivalent Resistance of circuit = 1 0 + (2 0 × 2 0/2 0 + 2 0) + 1 0 = 1 0 + 1 0 + 1 0 = 3 0 Ω

Q. What will be the equivalent resistance of circuit shown in figure between two points $A$ and $D$ ?

$10 Ω$

$20 Ω$

$40 Ω$

Equivalent Circuit

Equivalent Resistance of circuit
$= 10 + \frac{20 \times 20}{20 + 20} + 10 = 10 + 10 + 10 = 30 Ω$
