Ohm's Law states that when the temperature remains constant, the current (I) flowing through a conductor is directly proportional to voltage (v), and inversely proportional to resistance (R).

The basic principle of the electromagnet is the electromagnetism. When the ferromagnetic iron core is coiled by a wire and a current is passed through the core, it produces a strong and magnetic field, and turns the setup into a magnet. By changing the current, one can change the strength of the magnetism, and when the current is switched off, the magnetism disappears.

The process of creating the electric current in a conductor by moving the conductor through the magnetic field or by changing the magnetic field around the conductor is known as the Electromagnetic Induction.

After passing the JAC 12th exam 2025, students have several options based on their interests and career goals. They can pursue higher education in fields like engineering, medicine, commerce, or humanities by enrolling in courses such as B.Tech, MBBS, B.Com, BA, or B.Sc. Those interested in professional careers can opt for Diploma programs, vocational courses, or certifications in areas like hospitality, IT, and management. Additionally, students can prepare for competitive exams like JEE, NEET, NDA, or government job exams.

The sum of a magnetic field that passes through a given surface area is called the magnetic flux. 

As per the Faraday's Law of Induction, when a conductor is exposed to a changing magnetic field, a circulating electric current is induced, it is called the Eddy current. The Eddy currents have many applications including - non-destructive testing and induction furnaces.

The process of creating the electric current in a conductor by moving the conductor through the magnetic field or by changing the magnetic field around the conductor is known as the Electromagnetic Induction.

Yes, the university mandates students to submit proof of English language proficiency to be eligible for admission at Nanyang Technological University. The required scores for IELTS are as follows:

• TOEFL iBT: Overall score of 90 or higher
• IELTS Academic: Overall score of 6.0 or higher (with minimum 6.0 in writing)
• PTE Academic: Overall score of 55 or higher
• SAT: Overall score of 1250 or higher
• ACT (Writing section): Overall score of 30 or higher

The common mistakes can be - using the formula incorrectly, before applying the formula students not simplify the expression, in Binomial Expansion, sometimes they forget to include the fractional and negative exponents, and using incorrect values for a, b, and n.

The Binomial model is known as the Lattice Model or Binomial Option Pricing Model.
