Poor Homer is the lone "coulomb" in a bar full of "mA·h" (milliampere-hours)! It's like showing up to an electrical engineering party with the wrong unit! 🔌⚡
For the uninitiated lab rats: a coulomb measures electric charge, while milliampere-hours measure battery capacity. They're related but different - like bringing a protractor to a ruler fight! Homer's face says it all: "I've made a terrible miscalculation." The electrical engineering equivalent of wearing socks with sandals!
