Anda telah mempelajari bahawa elektron yang berada dalam suatu konduktor boleh bergerak, mengalir menghasilkan arus elektrik.
Namun elektron asalnya dijumpai bukan melalui suatu konduktor, tetapi melalui suatu pancaran yang terhasil dalam eksperimen sinar katod. Tonton video di bawah untuk melihat lebih lanjut tentang bagaimana manusia menjumpai bahawa sebenarnya terdapat elektron di dalam atom, sudah lama diletakkan oleh Allah, akhirnya dijumpai manusia pada tahun 1897.
Penemuan elektron ini membuka suatu lembaran baharu dalam perkembangan teknologi manusia, alhamdulillah.
Mari kita teroka, bagaimana penemuan elektron ini dimanfaatkan dalam bidang elektronik.
