Hey new to the forum

And learning to be an electrician.

I have a few questions about voltage drop.

I understand the formula and all that

for example if I had 25 led lights at 24w each spaced evenly over a distance of 65m fed off a type c 10 amp mcb

would the design current (lb) used in the formula be 10 amps or would it be the 24watts x 12 = 288watts and in amps that is 1.25A

so would my formula us the breaker size of 10 amps or the load of the lighting circuit for voltage drop?

so if it was in 1.5mm it would be

mV/A/m x IB x L /1000

29 X 1.25 x 65 /1000 = 2.3 volts

or would it be

29 x 10 x 65/1000 =18.8 volts
