Question

Find equivalent resistance between A and B in the combination shown in the figure:

Answer 1

we know that 12 ohm and 4 ohm resistors are in parallel so 1/12 + 1/4 = 1/3 the equivalent resistance of 12 ohm and 4 ohm resistors is 3 ohm. Then equivalent resistance between A to B will be 2 + 5 + 3 = 10 ohm. The equivalent resistance from A to B is 10 ohm

Answer 2

12ohm and 4ohm are in parallel so using formula we get their resulting resistance..... as 3ohm

now all the 3 resistors 2ohm ,3ohm and 5ohm are in series combination so the resulting resistance

or

resistance between A and B is 10ohm


hope it helps
