### What is Meant by the Equivalent Resistance?

In Physics, an equivalent Resistance is defined as the sum of the resistance of the resistors connected in a circuit. The resistors can be connected in series or parallel. Assume that R1, R2 and R3 be the three resistors
If these three resistors are connected in series, then the equivalent resistance is given by
Re = R1 + R2 + R3
If these three resistors are connected in parallel, then the equivalent resistance is given by
1/Re = (1/R1) +(1/R2) + (1/R3)
