Use the diagram above (a diamond/bridge arrangement of four resistors, each 100 ohm, between points P and Q) to answer this question. In the figure above, calculate the total resistance between P and Q if each of the resistors is 100 ohm
- A. 50 ohm
- B. 100 ohmCorrect
- C. 250 ohm
- D. 500 ohm
Explanation
In this symmetric bridge-like network of equal resistors, the equivalent resistance between P and Q works out to 100 ohm.
