A temperature changes converts changes of temperature into
Correct answer: A. Electrical voltage
- A. Electrical voltage
- B. Light signals
- C. Sound signals
- D. All of above
Explanation
Temperature changes can indeed be converted into electrical voltage using devices called temperature sensors or thermometers. These sensors utilize temperature-dependent electrical properties to generate a voltage signal proportional to the temperature change. This voltage signal can then be measured and used for various applications such as temperature monitoring, control, and data acquisition.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
