Charging an object without direct contact between the object and the charge

Charging by induction

100

Current that flows from the positive side of the battery to the negative side.  This is the way the current is drawn in circuit diagrams, even though it is wrong.

Conventional current

An object is not one of these because its atoms are not aligned.

magnet

200

A small "package" of light energy that acts like a particle

Photon
200

Charging an object by allowing it to come into contact with an object that already has an electrical charge.

Charging by conduction

200

If a circuit has low voltage how would you get a lot of energy from it?

You would have to put a lot of current through it.

In most chandeliers today, when one light bulb goes, out, the rest stay lit.  These light bulbs are wired in a _______________.

parallel

Charging by this method results in the same charge as the rod used to charge an object.

Conduction
300

The amount of charge that travels past a fixed point in an electric circuit each second.

Electric current

You are blindfolded and handed two extension cords of equal length. Both have the same current running through them. The cord in your left hand is warmer than the one on your right hand.  Which one is thicker?

The cord in your right hand is thicker.

If a circuit has low voltage, is there a way to get a lot of energy from it? 

Yes

the photons they emit are not visible to humans.
400

The ability of a material to impede the flow of charge

Resistance

400

A material that easily carries a current.

Conductor

A physicist charges an object with a positively charged rod.  If the object develops a negative charge, how did the physicist charge the object?

The object was charged by induction.

400

For this question, you will draw the correct force exerted by the solid object with a solid arrow on the board.

Arrow pointing toward the dashed circle.

400

You cut a magnet in half - right between the north and south poles.  You now have this many south poles.

two

500

A circuit that does not have a complete connection between the two sides of the power source.  As a result, current does not flow.

Open circuit

When a glass rod is rubbed with a neutral silk cloth, the glass becomes positively charged.  The charged silk now has this charge. Why?

Negative, It lost electrons to the sild through friction.

The force between the south pole of one magnet and the south pole of another magnet is measure. If the distance between those magnets is suddenly doubled, how will the new force compare with the old one?

The force decreases by a factor of 4.

500

This is the type of force between the south pole of one magnet and the south pole of another.  

Repulsive
