Weerstanden in serie

Resistors are one of the most widely used electrical components, used to regulate the current in a circuit.

When the elements are connected in sequence one after the other, it is called a series connection.

In a series connection, if one element in the series breaks, it affects the other elements.

Consider three resistors in a series combination connected to a battery of voltage, "V" and current "I".

The combination of resistors can be treated as equivalent to a single resistor.

Since there is only one path for charges to flow through, the current flow through each resistor is the same. In contrast, the potential drop across each resistor varies depending on the value of the resistor.

The total potential difference across the terminals is the sum of individual potential differences.

The ratio of potential difference and the total current equals the equivalent resistance.

The expression for equivalent resistance can be generalized for the “n” number of resistors connected in the series.
