Answer: G = 1/R.
- A G = R
- B G = R<sup>2</sup>
- C G = 1/R
- D G = sqrt(R)
Correct answer: C. G = 1/R
Explanation: Conductance G = 1/R. Unit: Siemens (S) or mho. It measures how easily current flows.
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.
