please answer this ! ill mark brainliest

Answer 1

these two forces given in equation 2 and 4 attract each other. Hence two parallel wires carrying currents in same direction attract each other and if they carry currents in opposite direction repel each other.
AMPERE
Ampere is defined as that constant current which when flowing through two parallel infinitely long straight conductor of negligible cross section and placed in air at a distance of one metre apart, experience a force of two * 10 to the power minus 7.
2*10-7 newton per unit length of the conductor.
