Question

Two resistances of 100 Ω and 0 Ω are connected in parallel. The overall resistance will be:

• A. 100 Ω
• B. 50 Ω
• C. 25 Ω
• D. 0 Ω

Answer 1

The correct option is D

0 Ω

Effective Resistance $\left(R_e\right)$ when 2 resistors, let ($R_{1}and{R}_2$ )are in parallel is given by $\left(R_e\right)$ = $\frac{R_1\times R_2}{R_1+R_2}$

Given :
$R_1=100\Omega$
$R_2=0\Omega$
$\left(R_e\right)=\frac{100\times 0}{100+0}=0$
