See how voltage, current, and resistance connect in Ohm's Law (V = I Ă— R). Adjust battery voltage and circuit resistance to see how the formula and current flow respond in real time.
🎮 Try It
• Drag the Voltage slider to add or remove battery cells and watch the size of the letter V and current readout change.
• Move the Resistance slider to change the density of impurities inside the resistor graphic.
• Keep voltage steady while increasing resistance to observe how the current value (I) shrinks.
🎯 Your Mission
Make the current read below 9.0 mA, then above 9.0 mA, changing both voltage and resistance along the way. Finally, use a different voltage–resistance setting to return the reading to exactly 9.0 mA.
🌍 Real-World Connection
A volume control knob on a speaker changes the resistance in the audio circuit, reducing current to make sound quieter or increasing current to make it louder.
