Deck 2: Electron Theory and Ohms Law

Question 1

Matter is made up of smaller units called ____________________.

Answer 1

atoms

Question 2

The nucleus of an atom is made of protons and electrons.

Answer 2

False

Question 3

State Ohm's Law and calculate what the current would be in a circuit if a voltage of 24 volts was applied across a resistance of 6 ohms.

Answer 3

I = E/R.
I=24 volts/6 ohms. The current would be 4 amperes.

All electrons are alike regardless of the atom.

Question 5

Describe the three types of current.

Question 6

Draw a picture and describe the structure of an atom. Be sure to discuss the electrical charge of each part.

Question 7

The intensity of an electrical current is measured in _____________.

Question 8

The property of a material that causes it to oppose the movement of electrons is called ____________.

Question 9

In the atom, there is a relatively large mass at the center called the ____________________.

Question 10

All liquids, gases, and solids are examples of matter in different forms.

Question 11

Two objects with unlike charges repel each other.

Question 12

Anything that occupies space and has weight is called ____________________.

Question 13

Electrons flow through a device from the negative terminal of the source to the positive terminal of the source.
