Which characteristic of metals makes them important in electronic devices?

• A. Poor thermal conductivity
• B. Low melting point
• C. High electrical conductivity
• D. Brittle structure

Answer: (C)

Verified step by step guidance

1. Understand the properties of metals relevant to electronic devices. Metals generally have several characteristic properties such as electrical conductivity, thermal conductivity, melting point, and mechanical structure.
2. Recall that electronic devices rely on the efficient flow of electric current. Therefore, the key property to focus on is how well a material can conduct electricity.
3. Evaluate each option: Poor thermal conductivity is not typical of metals and would not be beneficial; low melting point is generally not true for most metals and is not directly related to electronic function; brittle structure is not a common characteristic of metals and would be disadvantageous.
4. Recognize that metals are known for their high electrical conductivity, which allows electrons to move freely through the material, making them ideal for wiring and components in electronic devices.
5. Conclude that the characteristic of metals that makes them important in electronic devices is their high electrical conductivity.
