Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

Why are inductors sometimes called “chokes”?
Because they limit or “choke” rapid changes in current, especially in AC circuits.
What is the relationship between inductors and magnetic fields?
Current in an inductor creates a magnetic field, and changes in that field induce voltage.
Which factors increase inductance? (Multiple answers possible)
 
Iron core
 
More turns
 
Larger coil area
 
Higher current
True or False: Increasing the number of coil turns increases inductance.
True
Why can inductors cause sparks when a switch is opened?
Because the induced high voltage tries to maintain current flow when the circuit is suddenly broken.
Give one real-life device where an inductor is essential and explain why.
In power adapters or SMPS, inductors store and transfer energy efficiently during switching.
Why are inductors often used in power supplies?
To smooth current, reduce ripple, and filter noise.
what happens when current through an inductor is suddenly switched off?
There can be a voltage peak because of the collapsing magnetic field trying to keep the current balance.
Inductors work because of chemical reactions inside them.
 
False
 
True
An ideal inductor allows DC current to pass once steady state is reached.
 
True
 
False
Inductors store energy permanently.
 
False
 
True
An inductor resists changes in current.
 
True
 
False
Which component behaves most like an inductor?
 
Battery
 
Water tank
 
Flywheel
 
Switch
What happens to current in an inductor when voltage suddenly increases?
 
It changes gradually
 
It changes instantly
 
It decreases to zero
 
It reverses direction
Which unit is used to measure inductance?
 
Henry
 
Farad
 
Ohm
 
Tesla
What is the main function of an inductor?
 
Store energy in a magnetic field
 
Store energy in an electric field
 
Increase voltage
 
Block all current
