فى الشكل المقابل وصلت المقاومتان A.B معا على التوازى

ثم وصل المجموعة على التوالى مع مقاوتة ثالثة C

وبطارية قوتها الدافعة الكهربية 18V فاذا كانت

المقاومات A . B. C هى 7\Omega.6\Omega.3\Omega

على الترتيب ...فاحسب مع اهمال المقاومة الداخلية للبطارية:

ا- المقاومة الكلية

ب- شدة التيار المار فى الدائرة

ج- شدة التيار المار فى كل من المقاومتين A.B

وصلت ثلاث مقاومات \Omega1.\Omega3.\Omega6 بمصدر تيار كهربى وكانت شدة التيار الكهربى المار

فى كل مقاوة 0.3A . 0.2 A. 0.1 A على الترتيب ... وضح بالرسم كيفية توصيل تلك

المقاومات ثم احسب المقاومة الكلية للدرائرة الكهربية .

V1=6×0.1=0.6V V2=3×0.2=0.6V

V3=1×0.3=0.3V

\therefore المقاومتان 3\Omega.6\Omega متصلتان على التوازى والمقاومة

1\Omega متصلة معهما على التوالى ويكون شكل الدائرة كالاتى :
