2.8 Power and energy in resistive circuits
2.8 Power and energy in resistive circuits We now consider the power and energy absorbed by resistors and supplied by sources in more detail. Recall that a voltage drop (a decrease in electric potential) across a circuit element in the direction of positive current flow represents energy absorbed. This is the case when current moves through a resistor.

By optimising inductor design, it''s possible to increase the initial stored energy, helping to boost the overall energy efficiency of the circuit. Moreover, this concept holds importance in safety considerations as well. Inductors used in high-powered circuits can store a substantial amount of energy even when the circuit is turned off.
If inductor can store energy why not a current carrying wire?
$begingroup$ @VarunChandra The complete circuit is always a closed curve, otherwise current can''t flow around it. If you try to think about "a straight wire carrying current" but ignore how the current gets into one end of the wire and out of the other, you are leaving out an important part of the physics.

Confusingly, I believe it''s the reciprocal 1/C that corresponds to the spring constant so a stiff spring is like a weak capacitor. For a given applied force (voltage), a stiff, high-k spring will displace very little (weak, low-C capacitor will store very little charge) and store 1/2kx 2 energy in the spring (Q 2 / 2C in the cap) . I also think of the resonant frequency as a …
