Hey young physicist! Ready to spark up your knowledge? Today, we're diving deep into the universe of electric potential! And don't worry, I got you covered with some electrifying real-world examples. Let's get charged up!

• Remember Topic B.5? We chatted about "voltage" or "pd" - these are potential differences.
• This is all about energy transfer when a charge moves. Think of it as an escalator - the steeper it is, the more energy you'd spend moving up or down.
• The fancy equation is: V = W/q (V is voltage, W is energy transfer, q is charge).
• A Volt (1V) is like saying you've transferred 1 Joule of energy for every Coulomb of charge!

Real-world Example: Think of charging your phone. The higher the voltage (V), the quicker it charges (because it's receiving more energy per unit of charge)!

• If you've peeked into Topic D.1, you've seen the gravitational potential - ΔVg = W/m. It's kinda like electric potential but with mass (m) instead of charge (q).
• Imagine you're on a trampoline. The closer you're to the center, the more you can jump and gain potential. But in the electric world, we say the zero of electric potential is way out at infinity. That's far!
