Electric Fields
This lesson covers:
- How electric fields affect charged particles
- How to draw electric field lines
- How a strong electric field can ionise air
________ charged objects have an electric field.
All
Some

Electric fields can be shown with electric field lines.
Field lines always point from:
Negative to positive charge
Positive to negative charge
|
True or false? Electric fields are strongest when close to the charged particle, and get weaker further away from the charged particle.
True
False
|
Particles with like charges , while particles with opposite charges .

The above diagram shows two charged particles and their field lines.
The two charged particles are:
Repelled by each other
Attracted to each other
|
Which of the following is true?
The electric field is weaker the closer you are to the charged particle
The electric field is stronger the closer you are to the charged particle
|
The above diagram shows two charged particles and their field lines.
The two charged particles are:
Attracted to each other
Repelled by each other

A strongly charged object can ionise the air, which means the air:
(Select all that apply)
Act as an electrical insulator
Emits light
Conducts electricity
Loses some of its electrons
