Integral Voltage-Current Relationships
The inductance may be defined
by the voltage-current relationship
Re-writing the above Equation
We apply integration. Let
us consider the limits to be placed on the
two integrals. The lower limit may be assumed
as current at initial time I
(t0),
therefore
By solving the above equation,
we have
or
We may write the integral
as an indefinite integral and include a
constant of integration k
where the constant of integration
depends on the initial conditions (t
= 0). The power absorbed in the inductor
is given by
