Resistors can be arranged in two basic forms in any circuit. These are parallel and series combination. To find out the equivalent resistance of the circuit or a branch in circuit in which resistors are in series, the resistors value is simply added up. For ex. if there are two resistors R1 and R2 of 5Ω of each in the circuit, then the equivalent reistance of the circuit Req is (R1*R2)/(R1+R2) i.e. 2.5Ω.
Fact: The equivalent resistance in parallel combination is always less than the smallest value.
Enter resistor values separated by commas.
