Superposition Formula

Superposition Formula

Understanding the Superposition Formula cam be challenging for a number of students. This does not mean that the formula will stay challenging forever. There are several formulas that a student has to learn in the educational journey. The Superposition Formula is one of them. Students need to be aware of all the aspects of the topic and related topics. This means they need to be thorough with the Superposition Formula. It can seem new and intimidating at first, but students encounter a number of some hiccups while learning. The textbooks are the main source of learning and information for students, but they also have limited information. This information about the Superposition Formula is good for the examinations, but might not be enough for other competitive examinations. Students need to rely on other sources, learning to have an entire idea of any topic like Superposition Formula.

The Superposition Formula is not tough to understand if learned with the help of the Extramarks platform. Students can understand faster and in the comfort of their home while learning from the Extramarks platform. One of the basic study material that students can access is the chapter wise revision notes and question banks. These learning materials cover all the aspects of the topic, and help the students revise and practise. Students can rely on Extramarks along with the textbooks to have a complete comprehension of the topics.

Another noteworthy aspect is the Learn-Practise-Test pedagogy of the platform. Students can learn about the topics, practise the questions, and then test themselves with an elaborate test series. This series includes previous year question papers, sample papers, and other important questions for the examination. Students can also attend live doubt-solving classes where they will be assisted by experience teachers and academic experts.

Principle of Superposition

The total current in any part of a linear circuit equals the algebraic sum of the currents produced by each source separately.

For example:

If the response produced by input A is X and that produced by input B is Y, then the response produced by input A+B is X+Y.

According to the Principle of Superposition

It is noted that the net displacement is the algebraic sum of displacements of individual waves.

Consider two waves are travelling alone and the displacement of these two waves can be represented by y1(x, t) and y2(x, t).

When these two waves overlap, the resultant displacement can be given as y(x,t).

y (x, t) = y1(x, t) + y2(x, t)

The resultant wave is calculated by considering the sum of wave functions of travelling waves

y1 = f1(x–vt)

y2 = f2(x–vt)


yn = fn (x–vt)
