Question

Plzzzz give me answer....

Answer 1

Firstly...in parallel...
1/6+1/2=1+3/6=4/6
Then in series...
4/6+6=4+36/6
40/6=20/3=6 2/3 ohm...c option

Answer 2

hey there,

I am meritkshitij here.

let's try it out

u can see that resistors of 6 ohm and 2 ohm are in parallel

so,equivalent resistance between them

1/Req = 1/6+1/2

= 1+3/6

=4/6

=2/3

so,Req=3/2 ohm.

now,this one and resistor of 6 ohm will be in series

so,Total eq resistance=3/2+ 6

=1.5 + 6

=7.5 ohm Ans.

thus,option c will be the right answer.

Thanks
