Determine the voltage on a copper conductor with a cross section of 1.5 mm2 and a length of 3 m, supplying current to the tile, if the current in the coil is 5 A.
The voltage is calculated by the formula:
U = I * (pL) / S
(since R = p * (l / S) is substituted in U = I / R)
We substitute:
U = 5 * 3 * 0.0175 / 1.5 = 0.175 W
Answer: U = 0.175 W
