1
Q

What are capacitors?

A

They are components that have a certain desired capacitance

2
Q

What is a dielectric?

A

It is a material that insulates the capacitor from each other

3
Q

What affects the charge of capacitor?

A
  • plate size
  • distance between plates
  • the applied voltage

(The absorption charge is proportional to the applied voltage)

4
Q

In capacitors how do they improve the practicality?

A

Instead of having two large plates they have several smaller plates side by side

5
Q

What is the dielectric?

A

It is the material that s put between plates to increase the strength of the electric field in the capacitor

6
Q

What is the rinciple of charging a capacitor?

A

The initial current will be extremely high and the voltage will be extremely slowly

7
Q

What happens to the voltage when a capacitor starts to charge?

A

The voltage rises

8
Q

What is the battery voltage?

A

The voltage of a resistor and capacitor together

The higher the capacitor voltage, the lower the resistor together
