When a certain inductor carries a current I, it stores 3.2mJ of magnetic energy. How much current (in terms of I) would it have to carry to store 9.2mJ of energy? I'/I = ? Please show all steps!
To understand the units of inductance, the potential energy
stored in an inductor, and some of the consequences of having
inductance in a circuit.
After batteries, resistors, and capacitors, the most common
elements in circuits are inductors. Inductors usually look like
tightly wound coils of fine wire. Unlike capacitors, which produce
a physical break in the circuit between the capacitor plates, the
wire of an inductor provides an unbroken continuous path in which
current can flow. When the current in...
