TransistorsA tiny electrically-controlled switch and amplifier — the single invention that everything digital is built from, and the part that drives a motor or amplifies an ECG.concept · 4 मिनट · foundationResistorsThe most common component on any board — it limits current and divides voltage, which is how a sensor's reading even becomes a number.concept · 3 मिनट · foundationOperational amplifiers & biosignal amplificationThe triangle that turns a microvolt heartbeat into something a computer can read — and the instrumentation amplifier built from it that makes ECG and EEG possible.concept · 4 मिनट · foundationInductors & coilsA coil that stores energy in a magnetic field — the part behind wireless charging of an implant, the gradient coils of an MRI, and the power supply inside every device.concept · 4 मिनट · foundationDiodes & rectifiersA one-way valve for current — it turns AC into DC, protects a circuit from reversed batteries, and absorbs the kick from a motor or solenoid.concept · 3 मिनट · foundationCapacitorsTwo plates that store charge in an electric field — the part that delivers a defibrillator's jolt and cleans up an ECG signal.concept · 4 मिनट · foundation
