1. What is Total Current in a Series Circuit?

Definition: This calculator determines the electric current flowing through a series circuit using Ohm's Law.

Purpose: It helps electrical engineers, technicians, and students analyze and design series circuits.

2. How Does the Calculator Work?

The calculator uses Ohm's Law formula:

Where:

• \( I \) — Current (amperes)
• \( V \) — Total voltage (volts)
• \( R \) — Total resistance (ohms)

Explanation: In a series circuit, the current is the same throughout, and can be calculated by dividing the total voltage by the total resistance.

3. Importance of Current Calculation

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

4. Using the Calculator

Tips: Enter the total voltage applied to the circuit and the sum of all resistances in the series path. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is current the same throughout a series circuit?
A: Because there's only one path for electrons to flow, the same amount of current flows through all components.

Q2: What happens if resistance is zero?
A: This would create a short circuit with theoretically infinite current (not physically possible and dangerous in real circuits).

Q3: How do I measure total resistance in series?
A: Simply add up all individual resistances: R_total = R1 + R2 + R3 + ...

Q4: Can I use this for AC circuits?
A: For purely resistive AC circuits, yes. For circuits with inductance or capacitance, you need to consider impedance.

Q5: What units should I use?
A: Voltage in volts, resistance in ohms, which will give current in amperes (amps).
