Interactive Quizzes

Quick quizzes to reinforce your learning

Question 1

What is the formula for self-induction?

$$\\epsilon = -L \\frac{di}{dt}$$
$$\\epsilon = -M \\frac{di}{dt}$$
$$\\epsilon = L \\cdot i$$

💡 Hint: Focus on what $L$ stands for in this context.

Question 2

True or False: Mutual induction occurs when the current in one coil does not affect another coil.

True
False

💡 Hint: Consider how one coil's magnetic field interacts with another.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A coil with a self-inductance of 3 H experiences a change in current from 5 A to 10 A over a period of 2 seconds. Calculate the induced emf.

💡 Hint: Identify the total change in current and divide it by the time period.

Challenge 2 Hard

Describe a real-world application of mutual induction. Illustrate with an example.

💡 Hint: Consider energy transfer without direct connections.
