If three resistors of 1 Ohm each connect in parallel to each other the resultant resistance is
Options
- A1 Ohm
- B1 3 Ohm
- C3 Ohm
- D9 Ohm
Correct answer
B. 1 3 Ohm
Step-by-step solution
For resistors connected in parallel, the equivalent resistance R_ eq is given by: 1 R_ eq = 1 R₁ + 1 R₂ + 1 R₃ Given R₁ = R₂ = R₃ = 1 , substituting the values: 1 R_ eq = 1 1 + 1 1 + 1 1 = 3 R_ eq = 1 3 Answer: 1 3 Ohm
