Series Resistance Formula:
| From: | To: |
Total resistance in a series circuit is the sum of all individual resistances connected end-to-end. In series configuration, the same current flows through each resistor, and the total resistance is simply the arithmetic sum of all resistor values.
The calculator uses the series resistance formula:
Where:
Explanation: In a series circuit, resistors are connected one after another, creating a single path for current flow. The total resistance increases with each additional resistor added to the circuit.
Details: Calculating total series resistance is fundamental in circuit design for determining current flow, voltage drops across components, power dissipation, and overall circuit behavior in electronic systems.
Tips: Enter resistance values in ohms for at least two resistors (R1 and R2 are required). Additional resistors R3 and R4 are optional. All resistance values must be non-negative numbers.
Q1: What happens to current in a series circuit?
A: The current remains the same through all components in a series circuit, as there is only one path for electron flow.
Q2: How does voltage distribute in series resistors?
A: Voltage divides proportionally across each resistor based on its resistance value, with higher resistance values dropping more voltage.
Q3: Can I add more than four resistors?
A: Yes, simply continue adding the resistance values using the same formula: R_total = R1 + R2 + R3 + R4 + R5 + ...
Q4: What are common applications of series circuits?
A: Series circuits are used in Christmas lights, voltage dividers, current limiting circuits, and various sensing applications.
Q5: How does power dissipation work in series?
A: Power dissipates individually across each resistor, with higher resistance values dissipating more power according to P = I²R.
