A good electric contact material should have all of the following properties except_____________?
Correct answer: A. high resistivity
- A. high resistivity
- B. high resistance to corrosion
- C. good thermal conductivity
- D. high melting point
Explanation
A good electrical contact should have low resistivity so that it produces little voltage drop and heating. Corrosion resistance, good thermal conductivity, and a high melting point are desirable properties.
