1. Resistors in Series and ParallelCh

2. Resistors : Series
In a series circuit, all components are connected end- to-end, forming a single path for electrons to flow.
When resistors are connected in series, the current in each resistor is the same.

3. Resistors: Series
Total current in a series circuit depends on how many resistors are present and how much resistance each offers.
The equivalent resistance can be used to find current.

5. Resistors : Series
Series circuits require all elements to conduct.

6. Resistors: Parallel
In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

7. Resistors: Parallel
The sum of currents in parallel resistors equals the total current.
Resistors in parallel have the same potential differences across them.

8. Resistors: Parallel
The equivalent resistance must always be less than the smallest resistance in the group of resistors.
