FLASHCARD QUESTION

Front

เส้นทางสำหรับกระแสไฟฟ้าเรียกว่า

Back

วงจร

Answer explanation

A route through which electrical current can flow is called a circuit. Voltage refers to the potential difference, watts measure power, and electricity is the general term for electric charge. Thus, the correct answer is circuit.

การเคลื่อนที่ของทั้งอิเล็กตรอนและความร้อน

Answer explanation

Conductors allow the movement of both electrons and heat. This means they can conduct electricity (via electron movement) and transfer thermal energy, making the first answer choice correct.

วงจรที่สมบูรณ์คืออะไร?

Back

เมื่อเส้นทางไม่ขาดจากลบไปบวก

Answer explanation

A complete circuit allows electrons to flow continuously from the negative terminal to the positive terminal. The correct choice highlights that the path for electrons must remain unbroken for the circuit to function.

เส้นทางที่อิเล็กตรอนเดินตามคืออะไร?

Back

วงจรปิด

Answer explanation

The unbroken path that electrons follow is called a closed circuit. In a closed circuit, electricity can flow continuously, allowing devices to operate. An open circuit, on the other hand, interrupts this flow.

หลอดไฟจะไม่ติดเว้นแต่จะมี

Back

วงจรปิด

Answer explanation

A light requires a closed circuit to allow current to flow. In a closed circuit, all components are connected, enabling the light to turn on. An open circuit, on the other hand, breaks the flow, preventing the light from lighting.

ตัวต้านทานทำอะไรในวงจร?

Back

จำกัดการไหลของกระแสไฟฟ้า

Answer explanation

The function of a resistor in an electrical circuit is to limit the flow of current. This helps protect components from excessive current that could cause damage, making 'to limit the flow of current' the correct choice.

FLASHCARD QUESTION

Front

วัสดุใดที่มักใช้เป็นฉนวน?

Back

ยาง

Answer explanation

Rubber is commonly used as an insulator in electrical circuits because it does not conduct electricity, preventing unwanted current flow. In contrast, materials like iron, copper, and aluminum are conductors.
