Pertanyaan (Lihat Simulator ISIS dioda bias maju) Berapakah arus yang melewati rangkaian keseluruhannnya? 20,1 mA Bagaimanakah kita menghitung kuat arus yang melalui rangkaian? Tentukanlah tegangan pada diode? 0.73 volt Tentukanlah tegangan pada LED! 2.26 volt Apakah fungsi tahanan pada rangkaian tersebut?

Vr = 2.01 volt Vd = 0.73 volt Vled = 2.26 volt
