Spínací tranzistor T z obr. má rovnicu priebehu napätia Uce po uzavretí tranzistora: Uce = 10 + 20 * e^-200t. Za koľko milisekúnd po rozpojení klesne v príklade napätie Uce na hodnotu 15V?
Ak bude vypínač (viď obr.) rozpojený, ukazuje ampérmeter hodnotu 3A. Ako sa zmení údaj ampérmetra ak zapojíme vypínač?
