Question

the effective resistance betweem the point A and B in the circuit given below is?

Answer 1

Heya!!

Start by RHS;

Simply uh can see 5 ohm and 15 ohms are in series & in Parallel with 20 ohm.

Hence 20 ohm is in parallel with 20 ohm.(attachment 1)

Hence 1/R = 1/20 + 1/20

=) 1/R = 1/10

=) R = 10 ohm

New diagram : attachment 2.

Now 10 & 6 are in series and in parallel with 48 ohm resistor.

Hence 16 ohm nd 48 ohm r in parallel. (attachment 3).

Hence 1/R = 1/16 + 1/48

=) 1/R = 1/12

=) R = 12 ohm.

New diagram in attachment 4.

Now see LHS;

10 & 8 ohms are in series & in Parallel with 9 ohm.

Hence 18 & 9 are in parallel. (attachment 5)..

=) 1/R = 1/9 + 1/18

=) 1/R = 1/6

=) R = 6ohm..

New diagram : uh will get one triangle in which resistance are in series : 14 + 12 + 6

= 32 ohm.

Hope it helps uh!!
