Standard Books Physics Combination of Resistors MCQ Question with Solution

Five equal resistances of 10 Ω are connected between A and B as shown in figure. The resultant resistance is

A

10 Ω

B

5 Ω

C

15 Ω

D

6 Ω

Correct Answer

Option B

Detailed Explanation

The circuit forms a combination of series and parallel resistances. Two sets of 10 Ω resistors are in series, each giving 20 Ω. These are in parallel with another 10 Ω resistor, resulting in an equivalent resistance of 5 Ω.
