Past Exam Questions for the 1st Class Telecommunications Construction Management Engineer Examination (2025/2024/2023/2022/2021/2020/2019) / Reiwa 7 to Reiwa 1 This app is for those aiming to pass the exam through self-study and repeated review of past questions, including studying during commutes. There are no in-app purchases or advertisements. You can repeatedly study on your mobile phone or tablet as preparation for the Reiwa 8 exam. For each question, you can quickly check the answer by clicking [Question ⇒ Answer]. The question text is also included on the answer page, making it easy to review. The "Learning Confirmation Test (R7-R1)" presents 10 questions randomly, allowing you to check your self-understanding. Let's study little by little on your mobile phone or tablet during your commute or breaks on the train or bus. *This includes past exam questions from 2024, 2023, 2022, 2021, 2020, and 2019. One of the most important things for obtaining a qualification is repeatedly reviewing past exam questions. By repeatedly reviewing past questions, you can understand the structure of the questions, the types of questions that appear, and your strengths and weaknesses. This allows you to create an exam preparation plan, including which areas to focus on and where to earn points. Find your own learning method and proceed with your studies systematically. [Example Problems] [Problem] R06-A-1 When a voltage V is applied to a parallel-plate air capacitor with an electrode distance d[m] as shown in Figure 1, a charge Q₀[C] is stored. If, as shown in Figure 2, the area of ​​the electrode plates remains unchanged, the distance between the electrodes is halved, and a dielectric material with relative permittivity εr=2 is inserted without gaps between the electrodes, and a voltage V is applied, which of the following is the appropriate magnitude of the charge Q[C] stored? However, the edge effects of the capacitor are not considered. [Problem] R06-A-2 Which combination of words is appropriate to fill in (A) and (B) in the following description of an annular iron core coil? "When the current flowing through a coil changes, the coil's [(A)] also changes, generating an induced electromotive force in the coil itself. In the annular core coil with a primary and secondary coil wound around it, as shown in the figure below, when there is no magnetic flux leakage, the change in the secondary coil's [(A)] is proportional to the change in the primary coil's current. Therefore, the induced electromotive force generated in the secondary coil is proportional to the change in the primary coil's current, and the proportionality constant at this time is called [(B)]." [Problem] R06-A-3 A voltmeter with a maximum scale of 50[V] shown in the figure below was connected to a 400[kΩ] series resistor, and a voltage of 40[V] was measured. The voltmeter showed a value of 8[V]. Which of the following combinations of the internal resistance rv[kΩ] of this voltmeter and the
