FAQs on Static Electricity vs Current Electricity

Question 1

1. What is the difference between static electricity and current electricity?

Accepted Answer

Ans. Static electricity refers to the build-up of electric charges on the surface of an object, usually due to friction or contact with another charged object. It does not flow as a current, but rather stays in one place. On the other hand, current electricity is the flow of electric charges through a conductor, such as a wire. It is the type of electricity that powers our homes and electronic devices.

Question 2

2. How is static electricity generated?

Accepted Answer

Ans. Static electricity is generated when two objects rub against each other, causing the transfer of electrons from one object to another. This transfer creates an imbalance of charges on the surface of the objects, resulting in one object becoming positively charged and the other becoming negatively charged. The build-up of these charges is what creates static electricity.

Question 3

3. What are the common examples of static electricity in everyday life?

Accepted Answer

Ans. Some common examples of static electricity in everyday life include:- When you rub a balloon against your hair and it sticks to the balloon.- When you shuffle your feet on a carpet and then touch a metal doorknob, resulting in a small shock.- When clothes cling to each other after being in the dryer.- When you touch a metal object after walking on a wool carpet and feel a small shock.

Question 4

4. How does current electricity flow in a circuit?

Accepted Answer

Ans. Current electricity flows in a circuit due to the movement of electrons. When a circuit is closed, meaning there is a complete path for the electricity to flow, electrons from the negative terminal of the power source (such as a battery) start moving towards the positive terminal. This movement of electrons creates a flow of electric charges, known as an electric current, through the circuit.

Question 5

5. What are the applications of current electricity in our daily lives?

Accepted Answer

Ans. Current electricity has numerous applications in our daily lives, including:- Lighting up our homes and powering electrical appliances.- Charging our mobile phones, laptops, and other electronic devices.- Running various modes of transportation, such as electric cars and trains.- Operating machinery and industrial equipment in factories.- Providing power for medical devices and equipment used in hospitals.
