During the transition of a substance to a superconducting state, only a small part of the conduction electrons move without experiencing resistance. The current in the superconducting solenoid of inductance L is "triggered" by connecting a constant voltage to the solenoid for a time t. Maximum current in solenoid I. Determine the upper limit of the amount of heat released in the solenoid when starting a current in it. Before the transition to the superconducting state, the resistance of the solenoid was R.
