Answer: Ohm.
- A Volt
- B Ampere
- C Ohm
- D Siemens
Correct answer: C. Ohm
Explanation: Resistance is measured in Ohms (omega). 1 omega = 1 V/A.
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.
