Electronic systems are integral to many engineered products. Key concepts include voltage, current, resistance, and the relationship V = I × R (Ohm’s law). You also need to recognize circuit symbols and understand series and parallel circuits. For example, in a series circuit, current is the same everywhere, while voltage divides.
电子系统是许多工程产品不可或缺的部分。关键概念包括电压、电流、电阻以及V = I × R（欧姆定律）的关系。你还需识别电路符号并理解串联与并联电路。例如，串联电路中电流处处相等，电压却会分配。
V = I × R
Practice calculating total resistance for resistor networks. For resistors in series, the total resistance is simply the sum. For parallel resistors, the reciprocal of the total equals the sum of reciprocals. Always include units (Ω for ohms, V for volts, A for amperes). Also look at input and output devices like thermistors, LDRs, buzzers, and LEDs.
练习计算电阻网络的总电阻。对于串联电阻，总电阻就是各电阻之和。对于并联电阻，总电阻的倒数等于各倒数之和。始终包含单位（Ω代表欧姆，V代表伏特，A代表安培）。还要研究热敏电阻、光敏电阻、蜂鸣器和LED等输入和输出器件。
Rₜₒₜₐₗ = R₁ + R₂ + R₃ (series)
1/Rₜₒₜₐₗ = 1/R₁ + 1/R₂ + 1/R₃ (parallel)
6. Mechanical Systems and Mechanisms | 机械系统与机构
Mechanical systems transmit and convert motion and force. Levers, linkages, gears (spur, bevel, worm), pulleys, and cams are common examples. You should calculate mechanical advantage (MA = load / effort) and velocity ratio, and understand how simple mechanisms change the direction or type of motion (e.g., rotary to linear).
机械系统传递并转换运动和力。杠杆、连杆、齿轮（直齿轮、锥齿轮、蜗轮）、皮带轮和凸轮是常见例子。你应计算机械利益（MA = 负载/动力）和速度比，并理解简单机构如何改变运动方向或类型（如旋转变直线）。
MA = Load / Effort
During your preparation, sketch and label common mechanisms, identifying the input, process, and output. Solve example problems such as finding the gear ratio for a gear train: divide the number of teeth on the driven gear by the number of teeth on the driver gear. This will reinforce your understanding of how speed and torque are altered.
在预习期间，绘制并标注常见机构，识别输入、处理和输出。解决例题，如计算齿轮系的传动比：用从动轮齿数除以主动轮齿数。这将强化你对如何改变速度和扭矩的理解。
Gear Ratio = Zdriven / Zdriver
7. Mathematical Skills for Engineering | 工程中的数学技能
Mathematical competence is vital in engineering. You will need to calculate areas, volumes, ratios, and percentages precisely.

9. Sustainable Engineering | 可持续工程
Sustainability is a core concern in modern engineering. You must understand the six Rs: rethink, refuse, reduce, reuse, recycle, and repair. Life cycle assessment (LCA) examines the environmental impact of a product from raw material extraction to disposal. Designers can minimize negative impacts by choosing renewable materials, designing for disassembly, and improving energy efficiency.
可持续性是现代工程的核心关切。你必须理解6R原则：重新思考、拒绝、减少、再利用、回收和修复。生命周期评估（LCA）考查产品从原材料提取到废弃处置的环境影响。设计师可以通过选择可再生材料、可拆解设计和提高能效来最小化负面影响。
Over the summer, research a common product like a smartphone or a plastic bottle and map its lifecycle. Consider the energy used in manufacturing, transportation, use, and end-of-life. This will help you answer examination questions on sustainability confidently.
暑期期间，研究一个常见产品，如智能手机或塑料瓶，并绘制其生命周期。考虑制造、运输、使用和报废各阶段消耗的能源。这将帮助你自信地回答有关可持续性的考试问题。
10. Preparing for the NEA and Exam Success | 为NEA和考试成功做准备
Your summer preparation should also focus on developing the skills needed for the NEA, such as sketching, CAD modeling (if accessible), and workshop safety procedures. Start collating a portfolio of design ideas and inspiration. For the written examinations, practice past paper questions under timed conditions, paying attention to command words like ‘describe’, ‘explain’, ‘analyse’, and ‘evaluate’.
