1. What is a Two Resistors Current Calculator?

Definition: This calculator computes the current flowing through a circuit with two resistors in series.

Purpose: It helps electrical engineers, students, and hobbyists determine the current in simple series circuits.

2. How Does the Calculator Work?

The calculator uses Ohm's Law formula for series resistors:

Where:

• \( I \) — Current (amps)
• \( V \) — Voltage (volts)
• \( R1 \) — Resistance of first resistor (ohms)
• \( R2 \) — Resistance of second resistor (ohms)

Explanation: The voltage is divided by the total resistance (sum of both resistors) to calculate the current.

3. Importance of Current Calculation

Details: Proper current calculation ensures circuit components operate within their rated capacities and prevents damage.

4. Using the Calculator

Tips: Enter the voltage in volts and resistances in ohms. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this work for parallel resistors?
A: No, this calculator is specifically for series resistors. Parallel resistors have a different calculation method.

Q2: What if I have more than two resistors?
A: Simply add all resistor values together in the denominator (R1 + R2 + R3 + ...).

Q3: What units should I use?
A: Use volts for voltage and ohms for resistance. The result will be in amperes (amps).

Q4: Can I use this for AC circuits?
A: Only for purely resistive AC circuits. For reactive components, you need to consider impedance.

Q5: Why is my current result so small?
A: Current decreases as total resistance increases. Large resistances will result in small currents for a given voltage.
