Electricity chapter 9

Electrons and protons have the same amounts of electrical charge.

• True

• False

Both electric current and voltage flow through common electric circuits.

• True

• False

Energy, not electrons, is sold to consumers by power companies.

• True

• False

Electrons and protons electrically repel each other.

• True

• False

Voltage behaves as an electric pressure.

• True

• False

The electrical force between two charged particles located 1 meter apart is 0.10N. What will be the force between these charges when located 2 meters apart?

• The same

• more

• less

A rubbed balloon will stick to to a wooden wall, which demonstrates charge

• transfer.

• potential.

• polarization.

• conservation.

A volt is a unit of electrical

• energy.

• pressure.

• current.

• resistance.

In an alternating current circuit, electron flow is

• slower than a snail's pace..

• almost the speed of light.

• simply back and forth.

As more resistors are added to a series circuit, the overall resistance

• decreases.

• remains the same .

• increases .
