A basic electrical circuit consists of a battery, a light bulb, a switch and wires connecting them. As soon as the switch is closed, even the light bulb is one mile away, the light bulb will be on IMMEDIATELY. This means that the electrical current (made of moving electrons) starts to run everywhere in the wire as soon as the switch is closed . Explain what happen and the source(s) of these free moving electrons.

A basic electrical circuit consists of a battery, a light bulb,
a switch and wires connecting them. As soon as the switch is
closed, even the light bulb is one mile away, the light bulb will
be on IMMEDIATELY. This means that the electrical
current (made of moving electrons) starts to run everywhere in the
wire as soon as the switch is closed.
Explain:
a) the origin of these free moving electrons (where do they come
from),
b) the force(s) that...

Consider a light bulb connected to a battery with wires. How
must the light bulb be connected in order for it to light?
Identify the relevant parts of the bulb and battery. Explain,
using the concept of potential difference, why and how your
configuration causes the bulb to light. Do not use the phrase
"complete circuit".

Three identical light bulbs are connected to a 30V battery in a
circuit. Bulb A is on main loop and closest to battery. Bulbs B and
C are in parallel and the junction is after Bulb A S1 is in the
loop with bulb B and S2 is in loop with bulb C
Initially switch 1 is closed and switch 2 is opened. When switch
2 is closed what happens to the brightness of bulbs A,B and C
Please explain

A circuit has a 2.9 V battery connected in series with a switch.
When the switch is closed, the battery powers two paths in
parallel, one of which has a resistor of resistance R1 = 80 Ω in
series with an inductor of inductance L = 1×10−2 H , while the
other has a resistor of resistance R2 = 230 Ω . What is the current
supplied by the battery at a time t = 0.25 ms after the switch...
