Question:
If three resistors of 1 Ohm each, connect in parallel to each other, then resultant resistance is
If three resistors of 1 Ohm each, connect in parallel to each other, then resultant resistance is
Options:
- a) 1 Ohm
- b) 1/3 Ohm
- c) 3 Ohm
- d) 9 Ohm
- a) 1 Ohm
- b) 1/3 Ohm
- c) 3 Ohm
- d) 9 Ohm
correct answer : b)
Explanation:
For parallel connection of three resistors of 1 Ohm each: 1/Req = 1/1 + 1/1 + 1/1 = 3. Thus, Req = 1/3 Ohm.
For parallel connection of three resistors of 1 Ohm each: 1/Req = 1/1 + 1/1 + 1/1 = 3. Thus, Req = 1/3 Ohm.
