Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
Pupils will develop knowledge of electronic components and a systems approach to designing. They will learn about different components and use these to build and test circuits for different purposes. They will design a system to control a greenhouse environment, considering the different variables.
Lesson Summary
You will learn to use calculations to determine the resistance, voltage or current at a given point in a control system.
Key Notes
- Ohm's law describes the relationship between voltage, resistance and current.
- We can use Ohm's law formula to calculate the value of voltage, current and resistance in electrical circuits.
- When calculating component values we often need to change the prefix.
- The technical specifications and dimensions of components are detailed on datasheets.
Vocabulary To Learn
- voltage (V): the measure of the 'push' from a battery that causes charge to be transferred around a circuit
- current (I): the rate of flow of charge in a circuit
- Ohms (Ω): the unit of resistance
- Resistance (R): is a property of a material, such as a metal, that opposes the flow of current
- Ohm's law: the relationship between voltage, current, and resistance in an electrical circuit
Common Mistakes To Avoid
- When we select a component, they are all the same.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Ohm's law describes the relationship between voltage, resistance and current. We can use Ohm's law formula to calculate the value of voltage, current and resistance in electrical circuits.
2. What does this key word mean in this lesson? 'voltage (V)'
the measure of the 'push' from a battery that causes charge to be transferred around a circuit.
3. Correct this common mistake.
Mistake: When we select a component, they are all the same. Correction: Different circuits and control systems require different value components. Changing one will affect the others.
