Questions
The unit of electric current "ampere" is the current which when flowing through each of two parallel wires spaced 1 m apart in vacuum and of infinite length will give rise to a force between them equal to
detailed solution
Correct option is B
Force per unit length on two parallel current carrying conductors is given by Fl= 10−7 × 2 i1i2a⇒Fl= 10−7 × 2 × 1 × 11 = 2 × 10−7 N/mTalk to our academic expert!
