Energy

Question 1

Electricity

Answer 1

Flow of electrical power charged from particles.

Question 2

Electrical Energy

Answer 2

Energy delivered by electrons, usually moving through a wire.

Question 3

Power Source

Answer 3

Anything that stores and transforms energy.

Question 4

Law of Conservation of Energy

Answer 4

States that it neither can be created, destroyed, only converted from one form of energy to another.

-when energy appears to be lost or used, it has actually just changed its form.

Question 5

Atom

Answer 5

Smallest part of everything and everything is made up of atoms.

Question 6

Joule

Answer 6

Unit or measurement for heat.

Question 7

Static Electricity

Answer 7

Build up of an electrical charge on the surface of an object.

Question 8

Conductor

Answer 8

Material that is used to connect the power source to the load.

Question 9

Insulator

Answer 9

Material that completely stops an electrical flow

ex. rubber, plastic, ceramics, and glass.

Question 10

Resistor

Answer 10

Material that makes it difficult for electricity to flow through

ex. steel and carbon

Question 11

Circuit

Answer 11

the loop in which an electrical current flows.

Question 12

Power Source

Answer 12

Where the energy of the circuit comes from
ex. battery

Question 13

Series Circuit

Answer 13

A circuit that has more than one load but only one path for the electrons to flow through. If there’s a break in the path, the circuit won’t work.

Question 14

Parallel Circuit

Answer 14

A circuit that has more than one load and multiple paths. If one light burns out, the others are still able to work.

Question 15

Load

Answer 15

Thing in a circuit which uses the electricity.

ex. light bulb, toaster, and blender

Question 16

Conductor

Answer 16

Material used to connect the power source to the load and back to the source again.

Question 17

Volatge

Answer 17

Voltage describes the pressure that pushes electricity. So voltage generates the flow of electrons through a circuit.

Question 18

Current

Answer 18

Is the rate of electron flow or current in an electrical conductor.
-measured in amps “A”

Question 19

Resistance

Answer 19

Measured in Ohms and determines how much current can flow.

The length of a cable increases the resistance. Wider cables have more space and fewer electron collisions.

Question 20

Ohm’s Law

Answer 20

States that the current through a conductor between two points is directly proportional to the voltage across the two points.

-ohms are a measure of resistance in an electrical current.
*used to demonstrate the relationship between current, voltage, and resistance.

Resistance = voltage divided by amps (I)
Amps = voltage divided by resistance
Voltage = amps x resistance

Question 21

What do series and parallel circuits have in common?

Answer 21

Both allow electrons to flow and make something happen.

Both need things like loads, conductors, power sources, currents, etc.

Question 22

Fuse

Answer 22

Safety device that can “blow” (melt) if the current flowing through it becomes too much.

Question 23

Parts of a circuit

Answer 23

(Basic)
Power source
Load
Conductor

Question 24

Electrical current

Answer 24

Refers to the movement of electrons through a circuit

Question 25

Current electricity

Answer 25

Electricity that moves from one place to another

Question 26

Electrical charges

Answer 26

If there are more protons in the atoms, the charge will be positive, if there are more electrons, the atom’s charge will be negative

Question 27

Transformation of energy

Answer 27

Energy is created and converted to other types.

Ex- water can create energy - mechanical in dams- and then they convert it into electricity.
