مطابق با شکل زیر، مداری شامل مقاومت، القاگر، خازن و منبع الکتریکی را در نظر بگیرید. با اعمال قانون کیر-شهف برای نمودار زیر، میتوان نوشت: رابطه بالا ما را به معادله دیفرانسیل زیر میرساند. فرض کنید که در حالت اولیه، خازن باردار نیست؛ بنابراین جریانِ I=dQ/dt متناسب با افزایش بارهای الکتریکی در خازن است. از این رو معادله بالا را میتوان بهصورت زی...
