Internal Resistance Calculator
Calculate internal resistance of batteries or sources
📖 Internal Resistance
The Internal Resistance estimates the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. It multiplies several factors: star formation rate, fraction with planets, habitable planets per star, etc.

💡 Tips & Information
- Formula: r = (EMF - V_terminal) / I
- Measured in Ohms (Ω)
- Lower is better for power sources
- Causes voltage drop under load
- Affects battery performance
