Question

In the following circuit diagram R1=R2=R3=R4=R5=3ohm. what is the equivalent resistance of the circuit?

Answer 1

equivalent resistance =R1+R2+R3+R4+R5

=3+3+3+3+3
=15ohms

Answer 2

$Hey \: there$
As we are given that -

R1 = 3

R2 = 3

R3 = 3

R4 = 3

R5 = 3

If the resistance are joined In series Then -

Re = R1 + R2 + R3 + R4 + R5

= 3 + 3 +3 +3 +3
= 15 Ohm

if the resistance are joined in Parallel combination then

$\frac{1}{Ref} \: = \frac{1}{3} + \frac{1}{3} + \frac{1 }{3} + \frac{1}{3} + \frac{1}{3} \\ \\ = \frac{5}{3} \\ \\ Ref \: \: = \frac{3}{5} \: ohm$
Hope this helps u !!
