Answer: ohmic.
- A non-ohmic
- B insulating
- C superconducting
- D ohmic
Correct answer: D. ohmic
Explanation: An ohmic conductor obeys V = IR with a constant R, giving a straight-line V-I graph through the origin (e.g. a metal wire at fixed temperature).
In series, the same current flows through both resistors; in parallel, the current splits between branches and the voltage across each resistor is the same.
Concept context
Ohm's law, resistors, Kirchhoff's laws, Wheatstone bridge, and cells.
