How a battery works
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
Is it really OK to supply more current than what the component is …
It is not talking about supplying singular components with unlimited current. A LED does not know how much current it wants by itself and will just keep pulling current until it blows. A LED with driving resistor is a circuit that knows how much current it wants and will only pull that much from the supply. $endgroup$ –
The Inductor and the Effects of Inductance on a Coil
The rate-of-change of current from 4 amperes to 0 in this simple example is given as being 10mS, that is the current (and also the magnetic field) decays from its old value to its new value over a time period of 10mS, thus dt = 0.01 seconds as given. The rate-of-change in current value is therefore: 4 – 0 = 4A, thus di = 4. Then the average ...
20.3 Electromagnetic Induction
If nature is symmetrical, then perhaps a magnetic field can create a current. In 1831, some 12 years after the discovery that an electric current generates a magnetic field, English scientist Michael Faraday (1791–1862) and American scientist Joseph Henry (1797–1878) independently demonstrated that magnetic fields can produce currents.

And the current is the same as when you would connect to ground without the capacitor: a short-circuit is a short-circuit.
