Ohm’s law describes how voltage, current, and resistance are related in an electrical circuit.

Key Points:

• Voltage (V): The electrical potential difference, measured in volts (V).
• Current (I): The rate of flow of electric charge, measured in amperes (A).
• Resistance (R): Opposition to current flow, measured in ohms (Ω).
• Formula: V = I × R
• For a constant resistance, current increases in direct proportion to voltage.

Why It Matters:

Ohm’s law is essential in designing circuits for electronics, household wiring, and electrical devices.

Tips for Using the Simulation:

• Keep two variables constant while changing the third to clearly observe relationships.
• Plot V vs I — the slope represents resistance (R).
• Try different resistances to see how the slope changes.
