What inductance would be needed to store `1.0 kWh` of energy in a coil carrying a `200 A` current. `(1kWh=3.6xx10^6J)`

Text Solution

AI Generated Solution

To find the inductance needed to store \(1.0 \, \text{kWh}\) of energy in a coil carrying a \(200 \, \text{A}\) current, we can use the formula for the energy stored in an inductor: \[ U = \frac{1}{2} L I^2 \] where: - \(U\) is the energy stored in joules, ...
