Compare the expressions for the energy stored in an inductor and the energy stored in a capacitor. Select the choices that explain the similarities indicated by the two expressions. The expressions are equivalent because ??=Δ?2. Each device stores an amount of energy that is inversely proportional to the physical dimensions of each device. The energy stored in each device is directly proportional to the square of a quantity involving charge. Calculating the energy stored in each device involves multiplying by...

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...
