A special kind of resistor can oppose the flow of an electrical current.
When electrons are rearranged in an object by an electric field, the object is charged by gaining or losing electrons. If an object gains electrons, it becomes negatively charged, and if it loses electrons, it becomes positively charged.
When an object gains electrons, it becomes negatively charged. When it loses electrons, it becomes positively charged. This change in charge affects the object's interactions with other charged objects.
If an object loses more electrons, it becomes positively charged, resulting in an increase in its electric field strength. Additionally, the distribution of the electric field around the object changes, with the field lines becoming denser and extending further outward due to the greater positive charge.
Charges are produced due to a source providing some energy. e.g cell. Firstly source creates potential difference between terminals and due to this electron at negative end of the terminal move towards positive terminal. In contrast, conventional current flows from positive to negative. In AC circuit electron stay at same place and just vibrate and energy is just passed around the circuit.
An electroscope is a device that can detect the presence of electric charge, including electrons. When a charged object is brought close to the electroscope, the electrons on the device are repelled or attracted, causing the leaves to diverge. This divergence indicates the presence of electrons on the object being tested.
When a charged object is brought close to a neutral object, the electric field from the charged object can cause the electrons in the neutral object to be attracted or repelled. This movement of electrons results in the neutral object becoming polarized, as the electrons are pushed away from or pulled towards the charged object.

gaining or losing electrons. If an object gains electrons, it becomes negatively charged; if it loses electrons, it becomes positively charged.
An object's electric charge is typically measured in coulombs (C). The electric charge of an object depends on the number of protons and electrons it contains. Protons carry a positive charge, while electrons carry a negative charge. The total charge of an object is the difference between the number of protons and electrons.
Neutral objects will polarize in the presence of a charged object, causing a shift in the distribution of electrons within the neutral object. This movement of electrons creates an induced electric field in the neutral object that opposes the external electric field produced by the charged object.
when an object gains or loses electrons
induction
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
Circuit... i think
Electrons move through a conductor in response to an electric field. They flow from an area of high potential to low potential, carrying electric current. The movement of electrons is random at the atomic level, but collectively they drift in the direction of the electric field.
Electrostatic induction involves the movement of electrons in neutral objects due to the same electric field produced by a charged object. When a charged object is brought near a neutral object, the electric field from the charged object can cause the electrons in the neutral object to move, resulting in a redistribution of charge.
