The point at which this leader terminates may be different from that of the original first leader. The separation between such subsequent channels was observed to be approximately a few kilometers on average. Electrical activity similar to that which occurs after the first return strokes may also take place after subsequent return strokes. Note, however, that branch components occur mainly in the first return strokes and occasionally in the first subsequent stroke. This is the case because, in general, dart leaders do not give rise to branches.

When the stepped leader reaches a height of approximately a few hundred or fewer meters from ground, the electric field at the tip of grounded structures increases to such a level that electrical discharges are initiated from them. These discharges, called connecting leaders, travel toward the downward moving stepped leader. One of the connecting leaders may successfully bridge the gap between the ground and the downward moving stepped leader. The object that initiated the successful connecting leader is the one that will be struck by lightning.

We represent the current in the two conductors as I1(t) and I2(t). e. 30), the force per unit length (in N/m) on conductor 2 due to the current in conductor 1 is (using Eq. 30)  FðtÞ ¼  μ 0 I 1 ðt Þ I 2 ðtÞ: 2πa ð3:32Þ The same force also acts on conductor 1. If the two currents are equal [say I(t)], then the force between the two conductors is FðtÞ ¼ a μ  0 I 2 ðtÞ: 2πa ð3:33Þ b I (t) I (t) q B magnetic field Current carrying conductor Fig. 9 (a) Current-carrying conductor located in magnetic field.
