Resistors in Series

Series Circuit

A circuit where components are connected one after another, resulting in the same current flowing through each component.

Kirchoff's Law

The total voltage in a series circuit is equal to the sum of the voltages across each resistor.

Total Resistance in Series (RT)

The sum of all individual resistances in a series circuit, calculated as RT = R1 + R2 + R3 + ...

Current in Series Circuits

The current is the same at all points in a series circuit.

Voltage in Series Circuits

The total voltage is equal to the sum of the voltages across each resistor.

Example Calculation of Total Resistance

To find total resistance in a series circuit, add the resistances: RT = R1 + R2 + R3 + R4.

Equivalent Circuit

A simplified representation of a circuit, used to analyze its behavior with respect to current and voltage.

Potential Difference (Voltage)

The difference in electric potential between two points in a circuit, measured in volts.

Resistors in Series

Resistors connected in series share the same current, and their total resistance can be calculated by summing their individual resistances.

Adding Components in Series

Increases the total resistance in the circuit.
