In a series circuit, all components are connected in a single path.The same current flows through each component in a series circuit.In a series circuit, the total resistance is the sum of all individual resistances.Using Ohm's law, we can calculate the current by dividing the total voltage by the total resistance.The voltage drops across each resistor can be calculated using Ohm's law.The sum of voltage drops across all resistors equals the battery voltage.In a parallel circuit, components are connected across multiple branches.Unlike series circuits, the voltage remains the same across all branches, while the current divides.To find the total resistance in a parallel circuit, we use the reciprocal formula.Let's substitute our values: one-sixth plus one-third plus one-half.After finding a common denominator and adding the fractions, we get one ohm.Now let's calculate the currents. The total current is voltage divided by total resistance: twelve amps.In the first branch, with six ohms resistance, the current is two amps.The second branch, with three ohms, carries four amps.And the third branch, with two ohms, carries six amps.Notice how the total current of twelve amps divides among the three branches based on their resistances.لنبدأ بتحليل هذه الدائرة المركبة التي تحتوي على مقاومات متصلة على التوالي والتوازي.نتبع استراتيجية منهجية لحل الدائرة المركبة. أولاً، نحدد الأجزاء المتوازية.نحسب المقاومة المكافئة للفرع المتوازي باستخدام قانون مقلوب مجموع المقلوبات.بعد تبسيط الفرع المتوازي، تصبح لدينا دائرة توالي بسيطة.نستخدم قانون أوم لحساب التيار الكلي في الدائرة.نحسب فرق الجهد على كل مقاومة باستخدام قانون أوم.أخيراً، نحسب التيارات في الفروع المتوازية.وهكذا نكون قد حللنا الدائرة المركبة بشكل كامل.
