عن طريق فرق الجهد الكهربائي وهو منطقة تحتوي على شحنات كهربائية موجبة ومنطقة تحتوي شنحنات كهربائية سالبه او منطقة تحتوي على شحنات ومنطقة لا تحتوي على شحنات
By means of electric potential difference, which is an area that contains positive electric charges, an area that contains negative electric charges, or an area that contains charges, and an area that does not contain charges.

التناسب بين الفولتية والتيار هو تناسب طردي اي كلما ازداد التيار ازداد فرق الجهر والعكس صحيح
The ratio between voltage and current is a direct proportion, i.e. the higher the current, the loudness difference increases, and vice versa.

هي الاعاقة التي تبديها الذرات لحركة الشحنات الكهربائية
It is the obstruction shown by atoms to the movement of electric charges.
