What is a Milliohm? 🔍
Imagine a superhero of tiny electrical resistance, here to save the day in circuits and electronics! A milliohm (mΩ) is one-thousandth of an ohm (Ω), which measures electrical resistance. It’s like measuring tiny fractions of a penny in a big pile of coins. 🪙 While ohms are great for everyday applications, milliohms are essential for precise measurements in electronics, batteries, and power systems. Think of them as the fine-tuning knobs that keep everything running smoothly. 🎛️
