Q.
The equivalent quantity of mass in electricity is
Electromagnetic Induction
Solution:
The equivalent quantity of mass in electricity is self- inductance.
Self-inductance of an inductor is referred to as the "inertia of electricity" .
Kinetic energy in Mechanics,
$K =\frac{1}{2} mv ^{2}$
where $m=$ mass of an object.
$v =$ velocity of the object.
The magnetic energy stored in an inductor,
$K '=\frac{1}{2} L I ^{2}$
where $L=$ self-inductance of the inductor and,
$I =$ current through the inductor.
So, from the above equation, we can conclude that self-inductance is equivalent to mass in electricity.
