الترانزستور transistor

الترانزستور هو عبارة عن أداة إلكترونية تتكون من ثلاث بلورات ملتصقة مع بعضها بحيث تكون البلورتين الطرفين من نفس النوع وتفصلهما بلورة من النوع الآخر. يعمل الترانزستور بطريقة تُدعى بـ (التبديل الميكانيكي التقليدي)، والتي تقوم بوصل أو قطع تدفق التيار الكهربائي، من خلال وصل أو فصل طرفي الأسلاك، حيث يحتوي الترانزستور على إشارة تقوم بإخبار الجهاز بالوصل أو الفصل، وهكذا يمكن تشغيل الجهاز أو إغلاقه، وبالتالي فإن الترانزستور يمتلك خاصية التحكّم.
