Question

The maximum resistance which can be made using four resistors each of $2\Omega$ is

• A. $2\Omega$
• B. $4\Omega$
• C. $8\Omega$
• D. $16\Omega$

Answer 1

The correct option is C

$8\Omega$

Step 1: Given data

Resistance of each resistor = $2\Omega$

Step 2: Formula used

We know, that maximum resistance is obtained when resistors are connected in series.

The total resistance when the resistors are connected in series is $R_S=R_1+R_2+R_3+R_4$

Step 3: Substitute values in the equation

$\Rightarrow R_S=2+2+2+2$

$\Rightarrow R_s=8\Omega$

Thus the maximum resistance which can be obtained by using four resistors each of $2\Omega$ is $8\Omega$.

Hence, option C is correct.
