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

Show that (1 kWh = 3.6 xx 10^6J ).

True or false 1kWh=3.6xx10^9 J

Give the expression for energy stored in an inductance coil carrying current.

Is what from the energy in a current carrying coil is stored?

The magnetic induction of the centre of circular coil carrying current of 1.4 A is 1.76 xx 10^(-6) N/A m then the circumference of the loop is

The magnetic induction of the centre of circular coil carrying current of 1.4 A is 1.76 xx 10^(-6) N/A m then the circumference of the loop is
