Important Note for Class 10 Science Unit 11
Remember that electricity and magnetism are interconnected phenomena. This fundamental principle in Class 10 Science Unit 11 explains how changing electric fields create magnetic fields and vice versa. Understanding this relationship is crucial for mastering electromagnetic concepts throughout Class 10 Science Unit 11.
Detailed Solutions for Class 10 Science Unit 11 Exercise
Let’s explore comprehensive solutions for key problems from the Class 10 Science Unit 11 exercise with step-by-step explanations:
Problem 1: Calculating Electrical Resistance
A conductor has a voltage of 12V across it and carries a current of 3A. Calculate the resistance of the conductor.
Solution: Using Ohm’s law formula R = V/I, where V = 12V and I = 3A. Therefore, R = 12/3 = 4Ω. This fundamental calculation is essential in Class 10 Science Unit 11 for understanding electrical circuits.
Problem 2: Understanding Magnetic Field Patterns
Describe the magnetic field pattern around a straight current-carrying conductor.
Solution: In Class 10 Science Unit 11, we learn that a straight current-carrying conductor produces concentric circular magnetic field lines around it. The direction of these field lines can be determined using the right-hand thumb rule, where the thumb points in the current direction and curled fingers show the magnetic field direction as covered in Class 10 Science Unit 11.
Problem 3: Application of Electromagnetic Induction
Explain how electricity is generated in a hydroelectric power plant using electromagnetic induction.
Solution: This demonstrates electromagnetic induction principles studied in Class 10 Science Unit 11. Flowing water rotates turbines connected to generators. Inside generators, coils rotate within magnetic fields, inducing electric current according to Faraday’s law. This principle from Class 10 Science Unit 11 explains modern power generation methods.
