    Hello, I have three questions on Induction Effects. Thanks in advance for your assistance. Q1.) Consider the inductor in the context of an energy storage device. The electric-power industry would like to find efficient ways to store surplus energy generated during low-demand hours to help meet customer requirements during high-demand hours. Perhaps superconducting coils can be used. How much energy, in kWh, could be stored in a 310 H inductor carrying a current of 370 A ? Q2.) The electric-power...
