Two long wires are hanging freely. They are joined first in parallel and then in series and then are connected with a battery. In both cases, which type of force acts between the two wires
- Option 1)
Attraction force when in parallel and repulsion force when in series
- Option 2)
Repulsion force when in parallel and attraction force when in series
- Option 3)
Repulsion force in both cases
- Option 4)
Attraction force in both cases
Answers (1)
As we learnt in
Force between two parallel current carrying conductors -
- wherein
I1 and I2 current carrying two parallel wires
a-seperation between two wires
When they are connected in parallel the current flowing through both are in same direction hence they attract each other. when they are in parallel they will tend to repel each other
Option 1)
Attraction force when in parallel and repulsion force when in series
correct
Option 2)
Repulsion force when in parallel and attraction force when in series
incorrect
Option 3)
Repulsion force in both cases
incorrect
Option 4)
Attraction force in both cases
incorrect
