Electrical Calculator

Hello! My name is Selwyn! from BSIT ELC-2B, and I created this website as my parallel activity for CS 211 course. This website helps electrical technology students learn basic concepts and calculate Voltage, Current, and Resistance using Ohm's Law. I hope this helps and have FUN!

Basic Electrical Terms

• Voltage (V): Electrical potential difference between two points.
• Current (I): Flow of electric charge through a conductor (Amperes, A).
• Resistance (R): Opposition to current flow (Ohms, Ω).
• Power (P): Rate of energy used (Watts, W). P = V × I
• Conductor: Material allowing electricity to flow easily, e.g., copper.
• Insulator: Material that blocks electricity, e.g., rubber.
• Circuit: Complete path for current including source and load.

Basic Formulas

Ohm's Law:
V = I × R
I = V ÷ R
R = V ÷ I

Power:
P = V × I

Tips for Electrical Students

• Always double-check your calculations before connecting a circuit.
• Use proper safety equipment when working with live circuits.
• Remember Ohm's Law: V = I × R. It’s the foundation for many calculations.
• Practice calculating Voltage, Current, and Resistance in different scenarios.
• Keep a record of your calculations for reference and study.
