Ohm's Law (in relation to space technology)
Ohm’s Law describes the relationship between voltage (electrical pressure), current (electric flow), and resistance (obstacle to flow) in a circuit. Mathematically, it’s expressed as V = IR. In space technology, this law helps engineers design reliable electrical systems for spacecraft, satellites, and instruments. For example, knowing the resistance of wires and components allows engineers to calculate the needed voltage to ensure proper current flow, preventing overloads or insufficient power. This understanding ensures electrical systems operate safely and efficiently in the harsh environment of space, where precise control of power is critical for mission success.
