In an lr circuit at t 0 is 20a
WebTo analyze an RC or L/R circuit, follow these steps: (1): Determine the time constant for the circuit (RC or L/R). (2): Identify the quantity to be calculated (whatever quantity whose change is directly opposed by the reactive component. For capacitors this is voltage; for inductors this is current). (3): Determine the starting and final values ... WebMay 6, 2024 · Now, when your teacher said that at t=0 the current is 0, it is probably because before that time, the current was 0. Typically, in examples like this, there is a switch that is open before t=0, and closes at t=0. It is the fact that the current was initially 0, …
