AQA GCSE Physics: Current, Potential Difference and Resistance

Introduces fundamental concepts of electricity including standard circuit diagram symbols, electric charge, current, potential difference (voltage), and resistance. Covers the relationship between these quantities (Ohm's Law) and the factors affecting resistance.

Water flows powerfully through a network of copper pipes and wooden channels, some narrow and some wide, leading to a small, spinning water wheel. A large, elevated water tank in the background provides the pressure, while a partially closed brass valve in the foreground creates a visible obstruction to the flow, all under warm, natural light.

Lesson#1
Welcome to this deck on the fundamentals of electricity. We'll explore the essential concepts of electric current, potential difference, and resistance. You'll learn how to recognise standard circuit diagram symbols, understand what each quantity represents, and see how they are all linked together by a famous equation. This is a core topic in GCSE Physics, so mastering these ideas is crucial.
Lesson#2
To talk about electric circuits, scientists and engineers use a special visual language made of symbols. A drawing of a circuit using these symbols is called a circuit diagram. This allows anyone to understand the layout and components of a circuit, no matter what language they speak.
Quiz#3
In a circuit diagram, what does a circle with a cross inside it represent?

A lamp

Quiz#4
In a circuit diagram, what component is represented by a simple rectangle?

A resistor

Quiz#5
What component is represented in a circuit diagram by a line with a break in it, and another line angled upwards from the break like an open gate?

A switch

Lesson#6
The power source in a circuit is often a cell or a battery. A single unit is called a cell. When you connect two or more cells together, you have a battery. The symbol for a cell is a long line and a shorter, thicker line next to it. The long line represents the positive terminal.
