Web3 jun. 2024 · And the voltage induced across them is given by the formula: $$ V_{ind} = L \frac{di}{dt}. $$ Suppose, the circuit was at steady state. So the current through the inductor is 1 A at t = 0-. At t = 0, I move the SW1 to position B. Now, using the above formula, the magnitude of the induced voltage across the inductor should be 1 V. Web3 sep. 2024 · 1. Suppose you have two identical inductors, except one has a right-handed winding, and the other has a left-handed winding. Ramp up the current through the right-handed inductor. This produces a changing magnet field which induces a voltage in the inductor. That's self-inductance. brown leather wedges shoes
