Answer: 0.1001 ohm.
- A 0.1001 ohm
- B 0.01 ohm
- C 1 ohm
- D 0.001 ohm
Correct answer: A. 0.1001 ohm
Explanation: Shunt S = G x Ig / (I-Ig) = 100 x 0.001 / (1-0.001) = 0.1 / 0.999 = 0.1001 ohm.
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.
