Question

who we draw resistor in this question? ​

Answer 1

Explanation:

( a) first we connect two resistance in parallel,then its equivalent resistance became

3 i. e,

Re = 1/ (1/6 + 1/6)

Re = 1/ (1/3)

Re = 3Ω

and then connect them in series combination

then Re = 3+ 6 = 9Ω

( b) In this case first we connect two resistance in series then Re = 12Ω and connect them in parallel combination then equivalent resistance became 4Ω

i. e, Re = 1/(1/12 + 1/6)

Re = 1/(1/4)

Re = 4Ω

I HOPE THIS MAY HELP YOU
