Resistance
Resistance is the opposition to the movement of charges flowing through a material. It is measured in ohms and varies depending on the material and its properties.
Resistance
The opposition to the movement of charges flowing through a material is called resistance. It is a property that determines how strongly a material resists the flow of electric current.
The opposition to the movement of charges flowing through a material is called resistance. Resistance is caused by collisions between the moving charges and atoms in the material, which convert some of the electrical energy into heat. It is measured in ohms (Ω).
Conductors
The current through a material can be changed by varying the voltage applied across the material. By adjusting the voltage, you can increase or decrease the current flowing through the material. Additionally, changing the resistance of the material can also impact the current flowing through it.

When electricity travels through an object, it causes the movement of electric charges within the material. This movement generates heat and light, which can impact the object's temperature or produce electromagnetic fields. The specific outcome depends on the properties of the object and the amount of electricity flowing through it.
When electrons are not allowed to pass through a material, the opposition to current flow is known as resistance. Resistance is measured in ohms and is determined by the material's properties such as its composition, length, and cross-sectional area.
Electrons flowing through a conductor encounter resistance, which causes them to lose energy in the form of heat. This resistance is due to collisions with atoms in the conductor, hindering the flow of electrons. Additionally, the electrons may also interact with impurities or defects in the material, further impacting their movement.
Conduction. This is the process by which heat is transferred through a material without the material itself moving.
