Equivalent resistance represents the total or overall effect off all resistors in the circuit.
 
For resistors R1,R2 and R3 connected in series, the effective resistance Re is given by
Re = R1+R2+R3
For resistors R1,R2 and R3 connected in parallel, the effective resistance Re is given by
(1/Re) = (1/R1)+(1/R2)+(1/R3)
 
Effective resistance implies a single resistance equivalent to the total resistance of all other resistors in the circuit.It is purely a resistive property.Equivalent resistance is defined between the two terminals or nodes of the network
