A problem in which we have to find equivalent resistance between two points.
Problem can be solved easily by application of some basic laws .
1) Apply some Known quantity of voltage source across the point where we have to find Equilavent resistance.
2) Assume some current flowing in circuit.
3) Applying current division rule..find current in all branches and lastly the Total current .
4) From Ohms law, We have V=IR
Rearranging Ohms law we get
R=V/I , using assumed voltage and total current we can find Equivalent Resistance between two points.
Alternatively this problem can be solved by Star- delta conversion formula.... But the above method is easy and useful for any problem of that kind..
