Welcome to Episode 90 of our Happy Learning series. Static electricity is a phenomenon that occurs when there is an imbalance of electric charges on the surface of objects. This imbalance can build up through friction, induction, or contact with other charged objects. When the charged objects come into contact or are close to each other, they can produce a spark or experience an attractive or repulsive force due to the presence of the electric field. Static electricity is responsible for common everyday occurrences like hair sticking to a balloon after rubbing it or the shock felt when touching a metal object after walking on a carpet.

Electrostatic precipitators are devices used in industrial settings to remove fine particles, like dust and smoke, from exhaust gases. They work by applying a high-voltage electric field to ionize the particles, giving them an electric charge. These charged particles then move towards and stick to oppositely charged plates, which are periodically cleaned to remove the collected material. This process helps reduce air pollution by capturing more than 99% of fine particulates.

Electric Field:

An electric field is a region around a charged object where other charged objects experience a force. It is a way to visualize and calculate the effect of electric charges on one another. The strength and direction of the electric field are represented by field lines, which point away from positive charges and towards negative charges. The electric field is measured in volts per meter (V/m).

Coulomb's Law:

Coulomb's Law describes the force between two charged objects. According to this law, the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. The force is attractive if the charges are of opposite sign and repulsive if the charges are of the same sign.

Electric Charge and Charging by Induction:

Electric charge is a fundamental property of matter that causes it to experience a force in an electric field. There are two types of charges: positive and negative. Charging by induction is a method of charging an object without direct contact. It involves bringing a charged object near a neutral object, causing a redistribution of charges within the neutral object. This separation of charges can then be fixed by grounding the neutral object, allowing it to gain a net charge opposite to that of the inducing object.
