| In this chapter, capacitors and inductors will be introduced (without considering the effects of AC current.) The big thing to understand about Capacitors and Inductors in DC Circuits is that they have a transient (temporary) response. |
In acest capitol, capacitoarele si inductorii vor fi introdusi (fara a avea in vedere efectele curentului alternativ). Cel mai important lucru care trebuie tinut minte despre capacitori (condensatori) si inductori in circuitele de curent direct este ca au raspuns temporar. |
| During the transient period, capacitors build up charge and stop the flow of current (eventually acting like infinite resistors.) Inductors build up energy in the form of magnetic fields, and become more conductive. |
In timpul perioadei temporare, condensatorii se incarca si opresc mersul curentului (in cele din urma comportandu-se precum niste rezistori cu rezistenta infinita). Inductorii acumuleaza energie sub forma campului magnetic, devenind astfel mult mai conductori. |
| In other words, in the steady-state (long term behavior), capacitors become open circuits and inductors become short circuits. |
Cu alte cuvinte, in starea stabila (comportamentul pe termen lung), condensatorii devin circuite deschise, iar inductorii devin scurt-circuite. |
| Thus, for DC analysis, you can replace a capacitor with an empty space and an inductor with a wire. |
In acest fel, pentru analiza unui circuit de curent direct, un condensator poate fi inlocuit de un spatiu gol, iar un inductor cu un fir electric. |
| The only circuit components that remain are voltage sources, current sources, and resistors. |
Singurele componente ale circuitului care nu se schimba sunt sursele de tensiune electrica, sursele de curent si rezistorii. |
| DC steady-state (meaning the circuit has been in the same state for a long time), we've seen that capacitors act like open circuits and inductors act like shorts. |
In starea stabila a unui circuit direct (care inseamna ca circuitul a fost in aceeasi stare pentru o perioada lunga de timp), am vazut ca condensatorii se comporta precum circuite deschise, iar inductorii se comporta ca si scurt-circuite. |
| The above figures show the process of replacing these circuit devices with their DC equivalents. |
Cifrele de mai sus arata procesul inlocuirii acestor circuite cu echivalentele lor de circuit direct. |
| In this case, all that remains is a voltage source and a lone resistor. |
In aceasta situatie, tot ceea ce ramane este sursa de tensiune electrica si un singur rezistor. |
