Question

Calculate resistance between A and B ​

Answer 1

firstly we will see that how many ways are there through which we can go from A to B and simplify the circuit

then we will make two points between A and B i.e O and P

then we will solve the circuit in series and we get 3 ohm

then we see OP And MN are in parallel.we solve them like this :-

1/ Rp = 1/3 + 1/1

1/Rp=1+3/3

1/Rp = 4/3

Rp = 3/4

Then all this circuit we get in series then we will solve it simply :-

1+3/4+1

we get 11/4ohn
