Constants Part A The electric-power industry is interested in finding a way to store electric energy during times of low demand for use during peak- demand times. One way of achieving this goal is to use large inductors. What inductance L would be needed to store energy E 3.0kWh (kilowatt-hours) in a coil carrying crnt I 300 A? View Available Hint(s) Submit

Answer #1

here,

energy = 3 kW.hr

I = 300 A

let the inductance is L

as the energy stored = 0.50 L * I^2

3 * 3600 * 1000 = 0.50 * L * 300^2

solving for L

L = 240 H

the inductance needed is 240 H

    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...
