• capacitor

A capacitor consists of two metal plates separated by an insulator called a ...................

• conductor

• insulator

• senser

• dielectric

Capacitor pulls the .......................... off one plate

and pushes them onto the other.

• electrons

• protons

• charges

• celerity

A touch screen works like a ..........................

• conductor

• insulator

• senser

• capacitor

At the back of a digital camera is a ......................



This is a grid of components that work like capacitors.

• conductor

• insulator

• senser

• charge coupled

The charge on each component is transferred to a circuit that produces ........................

• electric signal

• digital signal

• positive signal

• negative signal

The camera converts this signal into an .....................

• image

• electrons

• waves

• sound

There is a ......................... around the Earth.

• gravitational field

• electric field

• force field

• all are wrong

There is a ......................... around the charge

• gravitational field

• electric field

• force field

• all are wrong

What would happen in a capacitor if the dielectric was not made out of an insulator?

• the charges would remain separate

• the charges would not remain separate
