⚡ Ohm’s Law & Circuit Calculator – Online Electrical Engineering Tool

The Ohm’s Law & Circuit Calculator is a powerful online tool for electrical and electronics engineering students to calculate Voltage (V), Current (I), Resistance (R), and Power (P) instantly. It’s ideal for analyzing DC and AC circuits in labs and academic projects.

🔍 What is Ohm’s Law?

Ohm’s Law defines the relationship between Voltage, Current, and Resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage across it, provided the temperature remains constant.

⚙️ Ohm’s Law Formula:

V = I × R  
I = V / R  
R = V / I  
P = V × I
  

🧮 How to Use the Calculator:

1. Enter any two known values (Voltage, Current, Resistance, or Power).
2. Click the Calculate button.
3. The tool automatically finds the remaining parameters using Ohm’s Law.

💡 Example:

If Voltage (V) = 12 V and Resistance (R) = 6 Ω, Current (I) = V / R = 12 / 6 = 2 A Power (P) = V × I = 12 × 2 = 24 W

📘 Features:
