The electrical circuit consists of a coil with an inductance of 0.25 H and a resistor of 2 ohms, which are connected in parallel and connected to the EMF source through a switch. At some initial time, the key is opened. Determine the voltage across the resistor after 0.01 s. The EMF value of the source is 12 V, the internal resistance of the source is 1 ohm.

A detailed solution with a brief note of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I will try to help.
