1. What is Series Equivalent Resistance?

The equivalent resistance of resistors connected in series is simply the sum of all individual resistances. This is one of the fundamental principles of circuit analysis in electrical engineering.

2. How Does the Calculator Work?

The calculator uses the series resistance formula:

Where:

• \( R_{eq} \) — Equivalent resistance (ohms, Ω)
• \( R_1, R_2, \ldots, R_n \) — Individual resistor values (ohms, Ω)

Explanation: In a series circuit, the same current flows through all resistors, and the total resistance is the sum of all individual resistances.

3. Importance of Series Resistance Calculation

Details: Calculating equivalent resistance is essential for circuit design, analysis, and troubleshooting. It helps determine total current flow, voltage drops, and power dissipation in series circuits.

4. Using the Calculator

Tips: Enter resistance values in ohms (Ω). You can add multiple resistors using the "Add Another Resistor" button. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What happens to current in a series circuit?
A: The same current flows through all components in a series circuit.

Q2: How does voltage distribute in a series circuit?
A: Voltage divides proportionally to the resistance values across each resistor.

Q3: Can I mix different resistor values in series?
A: Yes, resistors of any values can be connected in series, and the equivalent resistance is always the sum of all individual resistances.

Q4: What is the power dissipation in series resistors?
A: Power dissipates according to P = I²R for each resistor, where I is the same for all resistors in series.

Q5: How does series resistance affect total circuit current?
A: According to Ohm's Law (I = V/R), increasing series resistance decreases the total current in the circuit.
