DC circuitsQuestion 642 of 1506

Element A has half the resistance of element B. How do their conductances compare?

  1. A has half the conductance of B.
  2. A and B have the same conductance.
  3. A has four times the conductance of B.
  4. A has twice the conductance of B.
Show answer

Correct answer: A has twice the conductance of B.

More resistance means less conductance, so half the resistance gives twice the conductance.
