FAQs on Electricity - General Science, Exam Preparation Video Lecture - General Awareness & Knowledge - Bank Exams

 1. What is electricity?
Ans. Electricity is a form of energy resulting from the movement of electric charge. It is commonly generated by power plants and can be used to power various devices and appliances.
 2. How is electricity generated?
Ans. Electricity can be generated through various methods such as burning fossil fuels, nuclear reactions, harnessing renewable energy sources like wind, solar, and hydro power, or even through chemical reactions in batteries.
 3. What are the different types of electric circuits?
Ans. There are two main types of electric circuits: series circuits and parallel circuits. In a series circuit, the components are connected one after another, forming a single pathway for current flow. In a parallel circuit, the components are connected in multiple branches, allowing current to travel through different pathways.
 4. What is the difference between AC and DC electricity?
Ans. AC (alternating current) and DC (direct current) are two types of electric current. AC continuously changes its direction, cycling back and forth, while DC flows in a single direction. Most homes and businesses use AC electricity, while batteries and electronic devices often utilize DC electricity.
 5. How does electricity travel through power lines?
Ans. Electricity travels through power lines in the form of high-voltage alternating current (AC). This AC current is transmitted at high voltages to reduce energy losses during long-distance transmission. Transformers are used to step up or step down the voltage as needed for distribution to homes and businesses.
