Question

Five resistances are connected as shown in the figure. The effective resistance between points A and B is:

• A. 4 \( \Omega \)
• B. 5 \( \Omega \)
• C. 10 \( \Omega \)
• D. 12 \( \Omega \)

Hint:

In series combinations, resistances add up. In parallel combinations, the reciprocal of the effective resistance is the sum of the reciprocals of the individual resistances.

Answer 1

The Correct Option is A

Step 1: Simplify the resistances.
Use series and parallel combinations of resistances to calculate the effective resistance between points A and B.
Step 2: Explanation.
The effective resistance is found to be 4 \( \Omega \) after combining the resistances in series and parallel.
Final Answer: \[ \boxed{4 \, \Omega} \]
