The video introduces a large inductor, highlighting its significance in electronics.

What is an inductor primarily used for in electrical circuits?

• To store electrical energy in a magnetic field

• To convert AC to DC

• To amplify signals

• To measure electrical resistance

Which of the following is a characteristic of a large inductor?

• It is lightweight

• It can store more energy

• It is used to decrease voltage

• It has a small magnetic field

What happens to the magnetic field when the current through an inductor increases?

• The magnetic field increases

• The magnetic field disappears

• The magnetic field remains constant

• The magnetic field decreases

In what type of circuits are inductors commonly used?

• Thermal circuits

• Optical circuits

• AC circuits

• Digital circuits

What is the effect of a large inductor on the current flow in a circuit?

• It reverses the current flow

• It slows down the change in current flow

• It has no effect on the current flow

• It speeds up the current flow
