Question

Find the equivalent resistance between A and B in given
combination of resistances. ?

Answer 1

Answer:

first you plus last resistor 1+2=3pi

then second step resistor are in parallel so 1/2+1/3=5/6pi

third step is 5/6+1+1 =5/6+2= 2.83333pi answer

if 1st resistor and the last 2 resistor equal to 1 then you can write this
