Basic Vocab

Question 1

Watt

Answer 1

Unit of power equal to volts x amps

Question 2

Voltage

Answer 2

A type of “pressure” that drives electrical change through a circuit

Question 3

Volt

Answer 3

Unit of potential difference (similar to pressure)

Question 4

Transformation

Answer 4

The change in energy from one type to another as in a battery, which changes chemical energy to electricity.

Question 5

Transfer

Answer 5

The movement of electrons from one place to another either by current of static.

Question 6

Static Electricity

Answer 6

The build up of electrical charges on a surface produced by the contact and separation of dissimilar materials.

Question 7

Series Circuit

Answer 7

A circuit that connects a source, load and conductors in a single loop. Any break in the circuit will stop the flow of the current.

Question 8

Resistor

Answer 8

A device used to control current by providing resistance

Question 9

Resistance

Answer 9

The degree to which a substance resists electric current.

Question 10

Parallel Circuit

Answer 10

A circuit that splits into branches, a break in one branch will not stop current in the other branches.

Question 11

Ohm

Answer 11

Unit of electrical resistance used to measure a material’s resistance to the flow of electric current.

Question 12

Ion

Answer 12

An atom or group of atoms that has either gained or lost electrons and therefore has an electrical change.

Question 13

Insulator

Answer 13

A material that opposes the flow of electric current

Question 14

Electron

Answer 14

A subatomic particle with a negative electrical change

Question 15

Electromagnet

Answer 15

A temporary magnet formed when electric current flows through a wire or other conductor

Question 16

Electricity

Answer 16

A form of energy produced by the flow or accumulation of electrons

Question 17

Direct Current (DC)

Answer 17

Electric current that flows in one direction only.

Question 18

Current Electricity

Answer 18

Electricity that flows through a circuit, or a continuous unbroken path.

Question 19

Conductor

Answer 19

A material through which current flows easily.

Question 20

Circuit

Answer 20

A path of conductors that an electric current follows.

Question 21

Capacitor

Answer 21

An electric circuit element used to store charge temporarily

Question 22

Battery

Answer 22

A device that uses chemicals to generate and store electricity.

Question 23

Ampere (amp)

Answer 23

A unit of electric current used to measure the rate of flow.

Question 24

Amperage

Answer 24

The number of electrons that pass a given point at a given time.

Question 25

Alternating Current (AC)

Answer 25

Electric current in which electrons repeatedly change direction.

Question 26

Ohm’s Law

Answer 26

A law stating that the direct current flowing in a conductor is directly proportional to the potential difference between it’s ends. Usually formulated a V=IR, where V is the potential difference, or voltage, I is the current and R is the resistance.
