By electrons
When certain materials are rubbed together, they can become electrically charged. These materials are typically non-metallic and include substances like rubber, plastic, and fur.
Insulators
Materials that can become electrically charged when rubbed together include wool, fur, glass, and rubber. These materials have a tendency to gain or lose electrons during the rubbing process, leading to a build-up of static electricity on their surfaces.
Materials that can become electrically charged when rubbed together are known as insulators. These materials include rubber, glass, plastic, wool, and fur. When rubbed together, the transfer of electrons between the materials creates an imbalance of charges, resulting in one material becoming positively charged and the other negatively charged.
When materials are rubbed together, electrons are transferred from one material to the other, resulting in a buildup of static electricity. This can cause one material to lose electrons (become positively charged) and the other to gain electrons (become negatively charged), leading to an imbalance of charges between the two materials.
Materials that become charged when rubbed together are typically non-metallic and have different electron affinities, meaning one material tends to attract electrons more strongly than the other. Common examples include plastic, rubber, glass, and fur. Rubbing these materials together causes a transfer of electrons, resulting in one material becoming positively charged and the other becoming negatively charged.
When two different materials are rubbed together, electrons can be transferred from one material to the other, causing one material to become positively charged and the other to become negatively charged. This occurs due to differences in the electron affinity of the materials and the ability to hold onto electrons.
When two materials are rubbed together, electrons can transfer from one material to another, causing one material to become positively charged and the other to become negatively charged. This is known as triboelectric charging and occurs due to differences in the materials' electron affinity and their ability to hold onto or give up electrons.
Insulators
When a cellulose rod is rubbed with a cloth, electrons are transferred between the two materials, causing the cellulose rod to become positively charged and the cloth to become negatively charged. This generates static electricity due to the charge separation, which can be observed by the attraction of the two materials or by a spark when they are brought close together and then separated.
When balloons are rubbed against tissues, they become charged with static electricity. The tissues also become charged, but with the opposite charge. This opposite charge attraction between the balloon and tissue causes them to stick together.
When two bodies are rubbed against each other, they can acquire static electric charges. For example, when a balloon is rubbed against a sweater, the balloon may become negatively charged while the sweater becomes positively charged. Similarly, when two different materials like glass and silk are rubbed together, the glass may become positively charged while the silk becomes negatively charged.
