Materials that carry current when a field is applied are:

  1. Vacuum gap
  2. Conductors
  3. Insulators
  4. Dielectric
Show answer and solution

Correct answer: B. Conductors

1. Some materials have charges free to move. 2. An applied field sets those charges moving. 3. Such materials are called conductors. 4. So the answer is conductors. _Source: syllabus Physics, Ch 3 'Current Electricity'_

If two identical slabs are joined end to end, the combined resistance is:

  1. Half of R
  2. Same as R
  3. Four of R
  4. Twice R
Show answer and solution

Correct answer: D. Twice R

1. Joining end to end doubles the length of the path. 2. Doubling the length doubles the resistance. 3. So the combination has twice the resistance. 4. The answer is twice R. _Source: syllabus Physics, Ch 3 'Current Electricity'_
