Question

Calculate the equivalent resistance
across the points A and B.​

Answer 1

Answer:

So...

$\frac{1}{5} + \frac{1}{5} + \frac{1}{5} \\ \\ = \geqslant \frac{3}{5}$

So, Req = 5/3

Option A is correct

Answer 2

All the three resistance are connected in series

So formula for series resistance

$\sf\ R_s= R_1+R_2+R_3\\ \\ \\ \implies \sf\ 5+5+5\\ \\ \\ \implies\sf\ R_s= 15\ Ohm$

$\therefore\sf Option\ (B)\ is\ the \ correct\ answer$
