Did you know?
Web8 de out. de 2024 · In circuitry, especially in the area of microelectronics (e.g., inside op-amps), sometimes we need to invert the direction of a current (to make the flowing in current a flowing out one and v.v. - the flowing out current a flowing in one) without changing its magnitude. In this way, the output current just follows, "copies" the input … WebWe can find the current in the circuits by substituting the given amounts of charge and time for each circuit into this equation. For circuit 1, we have 𝐼 = 2 8 1 4 = 2. C s A. So, we have found that the current in circuit 1 is 2 amperes. For circuit 2, we have 𝐼 = 9 3 = 3. C s A. The current in circuit 2 is 3 amperes.
