Ohm's law calculator & playground
Slide the voltage and resistance, watch the current and power change live.

// HOW IT WORKS
The idea in 30 seconds
- V = I × R, so I = V ÷ R and R = V ÷ I.
- Power (heat) is P = V × I.
- Double the voltage → double the current. Double the resistance → half the current.
