I WONDER - What Does A Capacitor Do In A Circuit?

Capacitors are small energy storage units in circuits, storing and releasing electrical energy as needed. They are used in devices like flash cameras to produce bright flashes by releasing stored energy quickly. A capacitor consists of two plates separated by an insulating material, storing energy in the form of an electric field between the plates.

What role do capacitors play in a circuit?

• They dissipate electrical energy as heat.

• They generate electrical energy.

• They store and release electrical energy.

• They convert electrical energy to mechanical energy.

How does a capacitor function in a flash camera?

• It stores energy and releases it gradually.

• It stores energy and releases it all at once.

• It converts light energy into electrical energy.

• It continuously supplies energy to the flash.

What is the primary purpose of a capacitor in a flash camera?

• To regulate the camera's power supply.

• To convert electrical energy to sound.

• To store energy for a quick release.

• To provide a steady light source.

What separates the two plates in a capacitor?

• A magnetic field.

• An insulating material.

• A conductive material.

• A vacuum.

In what form is energy stored in a capacitor?

• As thermal energy.

• As a magnetic field.

• As a chemical reaction.

• As an electric field.
