A steady current flows through an inductor. If the current is doubled while the inductance remains constant, the amount of energy stored in the inductor:.

Respuesta :

If the current is doubled while the inductance remains constant, the amount of energy stored in the inductor 2LI².

Energy stored in inductor

The amount of energy stored in the inductor is given as;

E = ¹/₂LI²

where;

  • L is inductance
  • I is current in the inductor

When the current doubles, the new energy stored in the inductor;

E = ¹/₂L(2I)²

E =  ¹/₂L(4I²)

E = 2LI²

Thus, if the current is doubled while the inductance remains constant, the amount of energy stored in the inductor 2LI².
