Physics Final Day 3

A tiny imbalance of charge on an object is called ____ electricity.

• inductive
• static
• contact
• charged

The positively charged particle in an atom is:

• an electron.
• a proton.
• a neutron.
• an electron cloud..

Object A is attracted to object B. If object A is positively charged, then object B is:

• positively charged.
• negatively charged.
• electrically neutral.
• a coulomb.

The motion of charges in wires, motors, light bulbs and other devices is best called electric:

• power.
• voltage.
• current.
• conductance.

In an electrical circuit, the term current refers to:

• resistance.
• potential difference.
• flowing charges.
• energy loss.

A device that uses chemical energy to push current in a circuit is called a:

• battery.
• voltmeter.
• ammeter.
• potentiometer.

Electrical current will pass easily through:

• an absorber.
• a conductor.
• a semiconductor.
• an insulator.

Which of the following could be a good conductor of electricity?

• A metal pot
• A ceramic coffee cup
• A piece of foam packing material
• A plastic spoon

If there is a break at any point in a series circuit, the current will:

• stop everywhere in the circuit.
• leak out of the break point.
• be decreased by one-half.
• continue through remaining unbroken circuit branches.

Which of the circuit diagrams shown in Figure 21-1A is a series circuit?

• I only
• II only
• III only
• I and II only
