(With Physics)
Find out what is electrostatic energy and answer the following questions.
1. How does the movement of electrons cause the build up of charge?
2. What happens when electrons are lost or gained?
3. List few instances where we experience static electricity in daily life.
Answers
1)With this movement of electrons, the materials lose their electrical neutrality, and static electricity is accumulated. The material that attracted the electron is negatively charged and the material from which the electron was lost is positively charged. This is the Mechanism for the Generation of Static Electricity
2)When an atom loses electron(s) it will lose some of its negative charge and so becomes positively charged. A positive ion is formed where an atom has more protons than electrons. In the opposite case when an atom gains electron(s) it becomes negatively charged (more electrons than protons).
3)(Some examples might include: walking across a carpet and touching a metal door handle and pulling your hat off and having your hair stand on end.) When is there a positive charge? (A positive charge occurs when there is a shortage of electrons.)
please mark my answer as brainliest follow me and please don't report it as spam as it is the correct answer
ans1) We call a collection of moving electrons an electric current, therefore a buildup of charge can drive a current. The electrons simply flow away from the pile and ultimately end up attached to atoms in the environment.
ans2) Atoms of elements can lose or gain electrons making them no longer neutral, they become charged. A charged atom is called an ion. When an atom loses electron(s) it will lose some of its negative charge and so becomes positively charged.
