Series Combination
In a series combination, components are connected end to end in a single path for current.
Practice This ConceptMain explanation
Teacher explanation
Since there is only one path, the same current passes through every component. The total resistance becomes the sum of individual resistances, and the supply voltage gets divided among the components. Series connection is simple, but one break stops the whole circuit.
Example
If 2 ohm and 3 ohm resistors are connected in series, total resistance is 5 ohm.
Simple analogy
Series means one road, one current.
Common confusion
Students often think current divides in series, which is actually the rule for parallel branches.
Exam tip
Remember one path, same current, and added resistance in series circuits.
