☆☆☆☆☆Electrons move onto the object, giving it a static charge.
Apex ;)
observations
the electrons get ripped off one object and held by the other
The rubbing moves electrons to the object that holds them more tightly.
they show wich way iron shavings would align themselves
They always make closed loops.
Electric field lines can either form closed loops or they can start and finish on isolated electric charges. Magnetic field lines always only form closed loops.
It is in parallel, so one light can be on while others are turned off.
It is measured in ohms. It is the opposition of movement of electric charge. It is related to voltage and current by Ohm's Law. Resistance is what builds up pressure and it can also generate heat as with friction.

In a series circuit the current is the same at every point. This is Kirchoff's current law.
at the atomic level because of the movement of electrons
A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.
False
