A capacitor will discharge because once a path is created there is a potential difference $V=Q/C$. But for an inductor it's $L\frac{di}{dt}$. Why would an inductor want to discharge once you connect it to a capacitor?
Inductors discharge due to the principle of electromagnetic induction. When a current flows through an inductor, it creates a magnetic field. When the current is interrupted or stopped, the magnetic field collapses and induces a voltage in the opposite direction, causing the inductor to discharge.
The time it takes for an inductor to discharge depends on its inductance and the resistance in the circuit. A higher inductance or lower resistance will result in a longer discharge time, while a lower inductance or higher resistance will result in a shorter discharge time.
When an inductor discharges, the energy stored in its magnetic field is released. This energy can be used to power a circuit or can be dissipated as heat in a resistor. The amount of energy released depends on the inductance and current in the circuit.
No, an inductor cannot discharge without a power source. In order for an inductor to discharge, there must be a change in current, which can only occur if there is a power source or if the circuit is connected to another circuit with a different current flow.
Inductor discharge is commonly used in electronic circuits to create a delay or to filter out unwanted signals. It is also used in devices such as transformers and motors to convert energy from one form to another. Additionally, inductor discharge is used in flash photography to create a brief burst of light.
