Circuit Calculator – Analyze Voltage, Current & Resistance

A circuit calculator helps you analyze electrical circuits by calculating voltage, current, and resistance using Ohm’s Law. It is one of the most fundamental tools in electrical engineering and electronics.

This calculator allows you to solve circuit problems quickly by using the relationship between voltage (V), current (I), and resistance (R).

Ohm’s Law Formula

The core equation used in circuit analysis is:

• I = V ÷ R
• V = I × R
• R = V ÷ I

Example

If a circuit has:

• Voltage = 10V
• Resistance = 5Ω

Then the current is:

• Current = 2A

Applications of Circuit Calculations

Circuit calculations are used in:

• Electrical circuit design
• Electronics projects
• Power system analysis
• Troubleshooting electrical faults
