1. Electrical Charge

There are two types of electrical charge, positive and negative. Positive and negative charges will attract, while like charges will repel each other. Also electrical charge is the fundamental property of matter.

2. Electrical Current 

Electrical Current is the flow of electric charge passing through a conductor, like wires. These wires carry the electricity to a certain point in a circuit. Making the electrical 

current like the flowing water to a Dam.

3. Electrical Circuit

A circuit board in an example of a Electrical Circuit. This allows the flow of electricity to pass, typically made up of conductive wires and traces. Basic electrical circuits typically includes a voltage source like a battery. 

4. Conductors of Electricity 

Conductors of electricity are things that allow electicity to flow through them easily. For example copper, silver, gold, and even water are conductors. Conductors of electricity are commonly used by eletricians to wire outlets in your home.

5. Insulator

An insulator is a material that doesn't easily conduct electricity. So rubber would be a good insulator.

6. Incomplete Circuit

An incomplete circuit means something isn't connected to transfer the electrical path. For example if there is a broken wire along a circuit the electricity won't transfer. Meaning there is an incomplete Circuit.

7. Complete Circuit 

A complete circuit is the opposite of an incomplete one. Meaning all the wires and connectors are properly put together allowing the electricity to freely flow, making it a complete circuit.

8. Series & parallel Circuits

Series & parallel circuits are both fundamental ways to connect electrical flow. But series circuits have a singular pathway to conduct the current, while parallel circuits have multiple ways to connect the electrical flow, keeping the voltage the same through all components.
