Electric charges
Electric charges are fundamental properties of particles, such as electrons and protons, that give rise to electric forces and interactions. There are two types of electric charges:
- Positive Charge: Protons carry a positive charge. The symbol for positive charge is “+”.
- Negative Charge: Electrons carry a negative charge. The symbol for negative charge is “-“.
Key points about electric charges:
- Like charges repel each other: Two positive charges or two negative charges repel each other.
- Unlike charges attract each other: A positive charge and a negative charge attract each other.
- Electric charges are conserved: In an isolated system, the total electric charge remains constant. Charges can neither be created nor destroyed, only transferred from one object to another.
- Quantization of electric charge: Electric charge is quantized, meaning it exists in discrete units. The smallest unit of electric charge is the charge of an electron, which is approximately -1.602 x 10^-19 Coulombs (C).
- Charge interactions are mediated by electric fields: Electric charges create electric fields around them, which exert forces on other charges within their influence.
The study of electric charges and their interactions is an essential component of electromagnetism, which is a branch of physics. It has wide-ranging applications in various fields, including electronics, telecommunications, power generation, and medical imaging, among others.

Case Study on AIIMS-SYLLABUS Physics syllabus Electric charges
Sure! Here’s a case study that illustrates the application of electric charges in a real-world scenario:
Case Study: Electrostatic Precipitator in Industrial Air Pollution Control
Background: Air pollution is a major concern in industrial settings. Various processes in industries release pollutants, such as dust, smoke, and fumes, into the atmosphere. These pollutants can have harmful effects on human health and the environment. To mitigate the impact of industrial air pollution, electrostatic precipitators are widely used.
Scenario: A manufacturing plant that produces cement is facing air pollution issues due to the release of fine dust particles during the production process. The management decides to install an electrostatic precipitator to reduce the emission of dust particles into the surrounding air.
Implementation and Functioning of Electrostatic Precipitator: An electrostatic precipitator is a device that uses the principles of electric charges to remove particulate matter from industrial emissions. Here’s how it works:
- Ionization: The electrostatic precipitator consists of two main components: a set of high-voltage electrodes and a collection plate. The electrodes are connected to a high-voltage power supply, creating a strong electric field between them.
- Charging: The dust-laden gas from the cement production process is passed through the electrostatic precipitator. As the gas flows through the device, the fine dust particles become electrically charged due to the strong electric field between the electrodes. The electric field ionizes the gas molecules, resulting in the generation of positive and negative ions.
- Particle Collection: The electrically charged dust particles are attracted to the collection plates, which are grounded and have an opposite charge. The charged particles migrate towards the collection plates under the influence of the electric field, effectively separating them from the gas stream.
- Cleaning and Disposal: Over time, the dust particles accumulate on the collection plates, forming a layer of captured pollutants. Periodically, the collection plates are cleaned or mechanically shaken to dislodge the captured particles, which then fall into a hopper for proper disposal.
Benefits and Impact: The installation of the electrostatic precipitator in the cement manufacturing plant has several benefits:
- Air Pollution Control: The electrostatic precipitator significantly reduces the emission of dust particles into the surrounding air, thereby reducing air pollution and improving air quality in the vicinity of the plant.
- Compliance with Regulations: By implementing effective air pollution control measures, the plant can comply with environmental regulations and standards set by regulatory authorities.
- Environmental and Health Protection: The reduction in air pollution helps protect the environment and the health of workers and nearby communities, minimizing the risk of respiratory issues and other health problems associated with airborne pollutants.
- Resource Conservation: The captured dust particles can sometimes be recycled or reused, reducing waste generation and conserving resources.
Conclusion: This case study demonstrates how the principles of electric charges and the application of electrostatic precipitators can be employed to control air pollution in industrial settings. By utilizing the electric field and charge interactions, electrostatic precipitators effectively capture dust particles and contribute to environmental sustainability and health protection.
