There are no specific guidelines for providing step-by-step solutions and explanations in the answers of the Electrical Engineering optional subject. However, there are some general principles that can be followed to ensure clarity and effectiveness in your answers.

Introduction:
- Start your answer with a brief introduction to the topic or question being asked. This will provide context and give the reader an idea of what to expect in the rest of your answer.

Step-by-Step Solutions:
- Break down the problem or question into smaller steps and provide a clear and concise solution for each step.
- Use bullet points to list each step and make it easy for the reader to follow along.
- Clearly explain each step, including any formulas, equations, or concepts that are relevant to the solution.
- Show all calculations and intermediate steps, if applicable, to demonstrate how you arrived at the final answer.
- Use proper notation and symbols to represent variables, units, and mathematical operations.

Explanations:
- Along with providing step-by-step solutions, it is important to explain the reasoning and logic behind each step.
- Clearly state any assumptions or simplifications you are making in the solution.
- Provide relevant examples or real-life applications to illustrate the concepts being discussed.
- Relate the solution to the broader context of the subject or field of electrical engineering.
- Use diagrams, graphs, or figures, if necessary, to enhance the understanding of the explanation.

Conclusion:
- Summarize the main points or steps covered in your answer.
- Restate the final solution or answer, highlighting its significance or implications, if applicable.
