Welcome to the GCSE Physics Ninja **Electricity **course.

These video lessons are based on question-and-answer flashcards. You can either make your own or save time by purchasing the printable flashcard set from the **shop**.

When you have completed this course, you will be able to...

- Describe and understand
**static electricity**. - Explain how to
**produce and detect**electrical charges. - Understand the nature of
**electric fields**. - Describe electric
**current**as a flow of charge and perform calculations. - Define
**potential difference**in terms of energy and charge. - Calculate the
**electrical work done**by charge as it flows through a component. - Recognise
**current vs. potential difference graphs**for various components. - Use the
**current, resistance & potential difference**equation in calculations. - Describe how the
**resistance of a filament bulb**varies with current. - Explain how
**resistance of a wire**varies with length and diameter. - Analyse
**series and parallel circuits**. - Find the total resistance of a series or parallel
**network of resistors**. - Describe and recognise common
**electrical components**. - Understand how
**potential dividers**work. - Appreciate the differences between
**analogue and digital signals**. - Analyse and design
**digital circuits**using logic gates. - Describe the characteristics of the
**mains electricity**supply. - Explain
**household electricity safety**precautions. - Calculate the electrical energy transferred using the
**power rating**of an appliance. - Understand that electrical energy can be measured in
**joules or kilowatt-hours**.
