Question

Find the equi. resistance between A and B. Please explain how can i solve these type of questions easily.​

Answer 1

Answer:

break the circuitfron that point from which u have to find resistence that make easy circut for u and easily u can solve it the circuit is in parallel or in series

hope it will help u

remember first change in ti in ideal circuit then solve these type of curcuit

Answer 2

Answer:

As under:

Explanation:

Case 1

1/r=(1/2)+(1/4)=3/4

r=(4/3) ohms

Case 2

1/r=(1/4)+(1/4)=1/8

r=8 ohms

Case 3

Same as Case 2

Case 4

(Two hexagons):

1/R1=(1/3)+(1/3)+(1/3)=1

R1=1 ohm

R2=1 ohm

1/R3=(3)+(1/3)+(1/3)

=3+(2/3)=11/3

R3=3/11 ohm

Answer:

R1+R2+R3=1+2+3/11

=36/11 ohms.
