What is the description of an optoisolator?

🔍 Key Concepts

• Optoisolator / optocoupler basic structure • How electrical isolation between circuits is achieved using light • Difference between a photosensitive device and unrelated components like capacitors or batteries

💭 Think About

• Which option contains two parts that can transfer a signal using light without a direct electrical connection? • Which choices include components that actually respond to light versus components that do not? • Think about what you would combine with an LED to allow one circuit to control another while keeping them electrically isolated.

✅ Before You Answer

• Identify which choice includes a light-emitting device (LED) plus a light-sensitive device • Confirm that both parts in the correct option are directly involved in light-based signal transfer • Eliminate options that include components (like capacitors or batteries) that do not inherently respond to light for signal isolation
