Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
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.

Question 1
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.
Question 2
Describe a real-world application of mutual induction. Illustrate with an example.
💡 Hint: Consider energy transfer without direct connections.
