Class 12 Physics Paper Examples

Some example questions are given below:

1. For a capacitor, the charging current is 0.4 A. Find the displacement current.

(a) Zero

(b) 0.6 A

(c) 0.8 A

(d) 0.4 A

Ans: We know the concept that the magnitude of displacement current and the charging current is equal.

So, Answer for the question is 0.4 Amperes (d)

Ans: Declines.

FAQs on TNHSC Class 12 Physics Question Paper 2020

Q1. What are the Numerous Examples of Current Electricity?

Ans: These are examples of current electricity:

  • Starting a car.

  • Turning on a light.

  • Cooking on an electric stove.

  • Watching tv.

  • Shaving with an electric razor.

  • Playing video games.

  • Using a phone.

  • Charging a cell phone, etc.

Q2. What is the Application of Nuclear Physics?

Ans: The presence of Nuclear Physics is everywhere in our day-to-day lives. It can be mentioned as:

  • Detecting smoke in our homes.

  • Testing for and treating cancer.

  • Monitoring cargo for contraband.

The above examples are the various methods that utilize nuclear physics. These techniques have made an impact on our safety, health and security.

Q3. What do you Mean by a Communication System?

Ans: The proper definition for a communication system can be illustrated as it is a gathering of distinct broadcasting networks, relay stations, tributary stations, transmission systems and terminal equipment. These procedures are capable of interconnecting and interoperating for producing a communication system.

Q4. Can you Explain Why the Light is an Electromagnetic Wave?

Ans: Many scientists have named light as electromagnetic radiation. These energy waves are recognized as electromagnetic (EM) in nature due to their oscillation. The oscillation generates the electric and magnetic fields. In light, the photon is available. As we know that the photons are packets of energy; that is why light is an electromagnetic wave.
