A shortage of electrons on a surface creates an electric what?
A shortage of electrons on a surface creates an electric charge imbalance or positive charge. This can lead to the attraction of electrons from neighboring surfaces to balance the charge and create an electric field.
What is an electric charge generated when materials are squeezed?
The electric charge generated when materials are squeezed is known as piezoelectricity. This phenomenon occurs due to the rearrangement of the crystal structure in certain materials, leading to the accumulation of positive and negative charges along the material's surface. Piezoelectric materials are commonly used in devices like sensors, actuators, and piezoelectric lighters.
What were electrical storms called?
The electric storm is commonly known as thunder.In an electrical storm, the storm clouds are charged like giant capacitors in the sky. The upper portion of the cloud is positive and the lower portion is negative. How the cloud acquires this charge is still not agreed upon within the scientific community. However, it could be explained as follows:When there is a charge separation in a cloud, there is also an electric field that is associated with the separation. Like the cloud, this field is negative in the lower region and positive in the upper region. The strength or intensity of the electric field is directly related to the amount of charge buildup in the cloud. As the collisions and freezing continue to occur and the charges at the top and bottom of the cloud increase, the electric field becomes more and more intense. it is so intense, in fact, that the electrons at the earth's surface are repelled deeper into the earth by the strong negative charge at the lower portion of the cloud. This repulsion of electrons causes the earth's surface to acquire a strong positive charge. The strong electric field, being somewhat self-sufficient creates a conductive path for the negative cloud bottom to contact the positive earth surface.
What is a neutral electric charge?
-a definition of uniform electric charge-A dispersed colloidal particle can adsorb electically caharaged particles(ions) on its surface. The charged species adsorbed on the surface of a given kind of colloidal particle may be either positive or negative
What is the basis for the statement that lines of electric force begun and end only on electric charges?
The basis for this statement lies in Gauss's Law, which states that the total electric flux through a closed surface is proportional to the total charge enclosed by that surface. As a result, electric field lines must either begin on positive charges and end on negative charges, or form closed loops in cases where there are no charges present.
A shortage of electrons on a surface creates an electric what?
A shortage of electrons on a surface creates an electric charge imbalance or positive charge. This can lead to the attraction of electrons from neighboring surfaces to balance the charge and create an electric field.
Does static electricity have negative electrons?
Static electricity refers to the accumulation of electric charges on the surface of an object. These charges can be positive or negative. Negative electrons are the subatomic particles that carry a negative charge and are often involved in the build-up of static electricity on objects.
What is an electric charge generated when materials are squeezed?
The electric charge generated when materials are squeezed is known as piezoelectricity. This phenomenon occurs due to the rearrangement of the crystal structure in certain materials, leading to the accumulation of positive and negative charges along the material's surface.

the buildup of electric charge on an object is type of electrsiy?
Static electricity.
How do you decide which number is greater when one number is negative and one number is positive?
ANY positive number is greater than any negative number. Imagine you are digging a hole, and piling up the dirt you remove from the hole. The hole represents negative numbers- it goes lower than the surface. The piled up dirt represents positive numbers- it is higher than the surface. The surface is zero- neither positive or negative.
Earth's surface has an excess amount of negative charge?
Earth's surface actually has an overall neutral charge, with positive and negative charges balancing each other out. Lightning, for example, results from the buildup of charge imbalances in the atmosphere, not on the Earth's surface.
What is static electrisity?
If electric charges are at rest then it is called static electricity. If we rub a glass rod with silk then glass rod is found to have positive static charges. And silk acquires static negative charge.
What is the electric charge that has accumulated on an object it referred to what?
The electric charge that has accumulated on an object refers to an excess or deficiency of electrons on the object's surface, leading to a net positive or negative charge. This accumulation of charge can be influenced by various factors such as friction, induction, or conduction.
Is the North Pole positive?
The North Pole does not have a positive or negative charge. It refers to the northernmost point on the Earth's surface.
What are the rules for electric field lines?
Electric field lines are drawn to represent the direction of the electric field at various points in space. They follow specific rules: they originate from positive charges and terminate on negative charges, they never intersect, the density of lines indicates the strength of the electric field, and they are perpendicular to the surface of a conductor at equilibrium.
How does separating materials cause static electricity?
When materials are separated, they can exchange electrons, leading to an imbalance of positive and negative charges on the surface of the materials. This imbalance of charges creates static electricity. When the materials are brought back together or interact with other objects, the stored electrical charge can discharge as static electricity.
What is direction of the electric fields field near the earth's surface?
The electric field near the Earth's surface typically points vertically downward, towards the Earth. This is because the Earth's surface is negatively charged and repels negative charges, causing the electric field to point towards the surface.
