Chapter 6 Electricity

The buildup of charges on an object is called

• static electricity.

• negative charge.

• static discharge.

• positive charge.

Clothes in a dryer acquire static cling by

• friction.

• static discharge.

• conduction.

• induction.

The loss of static electricity as electric charges move off an object is called

• conduction.

• static discharge.

• friction.

• induction.

Suppose you acquire a positive charge from walking across a carpet. You then touch a doorknob and receive a shock. This leaves you

• uncharged.

• negatively charged.

• electrically neutral.

• positively charged.

An instrument that can detect the presence of an electric charge is a(n)

• magnet.

• conductor.

• electroscope.

• generator.

A complete, unbroken path through which electric charges can flow is a(n)

• magnetic field line.

• magnetic pole.

• electric circuit.

• electrical resistance.

Materials that allow the charges of an electric current to move freely through them are called

• resistors.

• conductors.

• insulators.

• magnets.

An example of an insulator is

• rubber.

• iron.

• silver.

• copper.

The ampere is a unit of

• temperature.

• electric charge.

• electric current.

• magnetism.

What parts of the cell are used to connect an electrochemical cell to a circuit?

• wet cells

• electrodes

• electrolytes

• terminals
