📚 Ohm's Law Fundamentals

⚡ Voltage (V)

Electric potential difference between two points. Measured in Volts (V). It's the "electrical pressure" that pushes current through a circuit.

🔄 Current (I)

Flow of electric charge through a conductor. Measured in Amperes (A). One ampere equals one coulomb of charge per second.

🔌 Resistance (R)

Opposition to current flow. Measured in Ohms (Ω). Higher resistance means less current for the same voltage.

📐 V = I × R

Voltage equals current times resistance. This is the fundamental form of Ohm's Law.

🔄 I = V / R

Current equals voltage divided by resistance. Use this to find current when you know V and R.

🔌 R = V / I

Resistance equals voltage divided by current. Use this to find resistance when you know V and I.
