Below are sample questions representative of the exercises included on this worksheet and related 8.66 Select Materials for Insulators or Conductors skill assessments:

Problem 1Difficulty: Mastery
A battery-powered heater uses a heating coil. The goal is to convert electrical energy into heat efficiently within a compact length of wire. Which material is best for the coil?
ANichrome
BSilver
CAluminum
DCopper
Solution & Explanation:Nichrome’s higher resistivity makes it heat strongly for a given length and cross-section. Copper, silver, and aluminum have low resistance and produce less heating.
Problem 2Difficulty: Mastery
A circuit must operate at 1 kV with a 1 mm spacer in a humid room. Dielectric strengths: air ~3 kV/mm, glass ~10 kV/mm, rubber ~20 kV/mm. "Which insulator is best to maximize safety margin?,A. Glass | B. Rubber | C. Air | D. Aluminum,B,Rubber has the highest dielectric strength

Problem 3Difficulty: Mastery
A transformer needs a liquid that electrically insulates the coils but also removes heat by circulating. Which is the best choice?
ATransformer oil (insulating mineral oil)
BSaltwater
CLiquid mercury
DMetal shavings slurry
Solution & Explanation:Transformer oil is an electrical insulator and can carry heat by convection. Saltwater and mercury conduct electricity, and metal particles would short circuits.
