1. What is Series Connection of Batteries?

When batteries are connected in series, the positive terminal of one battery is connected to the negative terminal of the next battery. This configuration increases the total voltage while maintaining the same current capacity.

2. How Does the Calculator Work?

The calculator uses the simple series connection formula:

Where:

• \( V1 \) — Voltage of first battery (volts)
• \( V2 \) — Voltage of second battery (volts)

Explanation: In series connection, voltages add up while the current remains the same as for a single battery.

3. Importance of Series Connection

Details: Series connection is used when higher voltage is needed than what a single battery can provide. Common applications include flashlights, power tools, and electric vehicles.

4. Using the Calculator

Tips: Enter the voltage of each battery in volts. Both values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I connect different voltage batteries in series?
A: Yes, but it's generally not recommended as it can lead to uneven charging and discharging.

Q2: What happens to current in series connection?
A: The current remains the same as for a single battery in the circuit.

Q3: How many batteries can I connect in series?
A: There's no theoretical limit, but practical considerations like size, weight, and safety apply.

Q4: What's the difference between series and parallel connection?
A: Series increases voltage, parallel increases current capacity while maintaining voltage.

Q5: Is this calculator valid for different battery types?
A: Yes, the voltage addition principle applies to all battery types (alkaline, lithium, etc.).
