At your risk. Any battery must be connected to a suitable fuse to avoid burn or fire hazard.
A wire is a highway of electrons. In a conductor such as copper at room temperature some outer electrons have enough energy to leave the atom. So we have in a cable a sea of electrons.
On direct current, a stream in one direction the electrons may move quite slowly at say 5cm per second.
Why would then a light bulb connected to a 10 meter cable light immediately by connecting the other side of the cable to a battery?
The electrons next to the bulb that will almost immediately start moving.
The almost immediate is because light needs such a little time to travel 10m.
It is the electromagnetic wave that causes the electrons to move.
So they may move in some situations slowly but their cause of movement moves very fast.
Resistors impede the flow of electric current by electrons colliding with atoms. they lose energy and this energy is converted to heat. Sometimes we use resistors to cook our food in the kitchen.
Capacitors store electrons. They store energy in the form of electric field.
Inductors tend to keep the flow of electrons constant. Inductance behaves like a mass. If a mass is stationary it was to keep being stationary and reacts to change in it kinetic condition. If a mass is moving it reacts in trying to stopping it, accelerating it or decelerating it. Try stopping a train or a ship (large mass equivalent to large inductance). By stopping abruptly a mass for example by collision great forces are created. In a similar way a great voltage is created at the terminals of an inductor if we try to stop the current by disconnecting the circuit so we must never touch the terminals of an inductor. The spark we see is possibly by ionisation of the air by the large voltage.
A capacitor in series will cut bass frequencies
An inductor in series will cut high frequencies.
A capacitor in parallel will cut high frequencies.
