Calculate the current flowing through a copper conductor 10 m long and a cross-sectional area of 0.2 mm at a voltage of 6 volts.
| January 2, 2021 | education
given:
L = 10 m, S = 0.2 mm ^ 2, U = 6 V, p (copper) = 0.017 ohm * mm ^ 2 / m
find: I
decision:
I = (U * S) / (p * L) = (6 V * 0.2 mm ^ 2) / (0.017 Ohm * mm ^ 2 / m * 10 M) = 7 A
answer: I = 7 A
