Correct answer: C. Manganese
- A. Gold
- B. Silver
- C. Manganese
- D. Carbon
Explanation
Thermistors are typically made from mixtures of metallic oxides, with manganese being one of the common components. These oxides exhibit a strong temperature-dependent resistance, making thermistors suitable for various temperature sensing and control applications.

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.
