**A slightly long explanation of resistance.**

- Ohm’s Law
- Resistance
- Factors affecting resistance
- Joule Heating

*Let’s go!*

**The next concept we need to explore is potential difference.**

- Potential Difference
- V = W/Q
- Assumptions in circuits

- Electrical Power
- P = VI
- Power ratings

*Let’s go!*

**Our first step into the world of electricity.**

- Electric Charge
- Charge carriers
- Quantisation & Elementary charge

- Current
- Formula describing current in a conductor: I = nAvq

*Let’s go!*

**Let’s wrap up everything with know about electric fields:**

- Electric Potential Energy
- Electric Potential
- Potential Difference
- Relationship between Electric Potential & Electric Field Strength
- Graphs

*Let’s go!*

After our basic understanding of electric field strength, we can now take a (slightly) deeper look:

- Formula: E = kQ/r
^{2} - Graphs

**Let’s dig deeper into electric fields now.**

- Point Charges
- Coulomb’s Law
- Proportionality constant for Coulomb’s Law

*Let’s go!*

In my previous post, I explained uniform electric field strength & derived its formulae. Now let’s look at a few applications:

- Problems involving basic forces
- Problems involving motion of charges
- Utilising the conservation of energy

**This post covers:**

- Electric Field Strength
- Uniform Fields & when they occur
- Formula derivation

*Let’s go!*

If you read my post about fields, you should remember that fields and forces are influenced by certain properties of matter. In this chapter, we look at fields affected by the ELECTRIC CHARGE.

- Electric Forces
- Electric Fields
- Electric Conductors & Insulators
- Charging objects

**The final entry of the fields trilogy:**

- Field Potential Energy
- Field Potential
- How forces arise through potential differences

*Let’s jump in!*
