i need to know the answer to the exact same question
Electric charges can travel through solids, liquids, or gases. They can travel through conductors, insulators, and semiconductors.

Negative charges move easily through conductive materials such as metals, which have a high concentration of free electrons that can carry the charge. These materials allow for the flow of electrical current with minimal resistance.
In solids it is only the negative electric charges on electrons that move through the circuit. The positive charges on protons remain in their fixed positions in atoms. Electric current is a measure of the rate at which electric charges move past a given point in a circuit.
Conventionally electric current was assumed to be a flow of positive charges. But in reality especially in metals electric current is due to the flow of negatively charged electrons. So direction of conventional current is opposite to the direction of flow of electrons. But in case of liquids as well as solids electric current is due the flow of both positive and negative ions.
An isolated positive and negative can move for example in an electric or magnetic field. But in metals only the electrons can move since the positive charge is bound to the metal lattice by attractive forces.
In solids, electric charge is typically transferred through the movement of electrons within the material, either through direct contact or induction. By contrast, in objects with less resistance such as metals, charges can move more freely compared to insulators. Additionally, the presence of free electrons in conductive materials allows for easier transfer of charge compared to insulating materials.
Energy is easily transferred through mediums such as air, water, and solids. It can also be transferred through electromagnetic waves like light or through the flow of electric currents.
A gas cannot go through non-porous solids.
Electric current does not need a liquid. It can pass in solids, liquids, gases, and even empty space. If it passes through a liquid, the liquid is called an electrolyte.
Materials like metals are good conductors of heat, electricity, and sound due to the movement of free electrons within their structures. Light can be transmitted through materials like glass and air due to their transparent properties, allowing light to pass through them relatively easily. Sound can be transmitted through materials that allow for the vibration of molecules, such as air, water, and solids.
Yes, in fact any substance which has an atomic interface will both gain and lose charges by friction. For example is the wind blowing on the surface of the ocean. There are two fluids (Water and air) which are pushing against each other at a central location called the interface. The wind has a negative charge and picks up positive charges and ions from the water. This causes charging by friction between 2 non-solids.
