Answer 2

Question :-

▪ to find the equivalent resistance??

Solution:-

Mark the resistances as R1 , R2 and R3 as shown in the figure attached.

the resistances R2 and R3 are in series combination as the current flowing through them is equal..

☆ for series combination,

resultant resistance of R2& R3 = R2 + R3

=》 R (23) = 3 ohm + 3 ohm

=》 R (23) = 6 ohm

the resistance R1 and equivalent resistance of R2 and R3 are in parallel combination as the potential difference across their end is equal..

☆ for parallel combination,,

equivalent resistance [ R eq] =》

${ \bold{ \implies{ \frac{1}{r \: eq} = \frac{1}{r1} + \frac{1}{r23} }}}$

${ \bold{ \implies{ \frac{1}{r \: eq} \: = \frac{1}{3} + \frac{1}{6} }}}$

${ \bold{ \implies{ \frac{1}{r \: eq} \: = \frac{3}{6} }}}$

=》 R eq = 2 ohm

• therefore ,

the equivalent resistance is equal to 2 ohm
