Question

Effective resistance of two 8$\Omega$ resistors in the combination.

Answer 1

Hint : Use the formula of equivalent resistance in parallel

Step 1 : Evaluating equivalent resistance

Given: Resistance of each resistor = $8\Omega$

$\frac{1}{R_{eq}}=$ $\frac{1}{R_1}+\frac{1}{R_2}$

$\frac{1}{R_{eq}}=$ $\frac{1}{8}+\frac{1}{8}$

$\frac{1}{R_{eq}}=$ $\frac{1}{4}$

$⟹$ $R_{eq}=4\Omega$

Effective resistance of two $8\Omega$ resistors is $4\Omega$.
