HELP PLS ILL GIVE U BRAINLIST Which of the following is NOT a term used to describe the conductivity of materials ?

A: Semi Insulator
B: Insulator
C: semiconductor
D: conductor

​

B. insulator

hope this was helpful

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
