Question

What will be a resultant resistance when four resistance conected in series each 1 ohm​

Answer 1

Answer:

4 ohm

Explanation:

The formula for finding the resultant resistance if resistors are connected in series :--

Re = R1+R2+R3+R4............n

i.e

Re = 1 + 1+ 1+ 1

= 4ohm Answer

Answer 2

Answer:

Resistance is represented by the sign$\Omega$The formula for finding the resistance in a parallel series is $\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+\frac{1}{R_4}$

The formula for finding resistance when resistors are connected in series is

$R_n=R_1+R_2+R_3+R_4$

Here, the all four resistors are of 1 ohm.

So, $R_1=1\;R_2=1\;R_3=1\;R_4=1\;$Putting values in the formula,

$1+1+1+1=4\omega\\ \therefore\ The\ total\ resistance\ in\ the\ circuit\ is\ 4\Omega.$
