Answer:
Vc = 2.41 v
Explanation:
voltage (v) = 16 v
find the voltage between the ends of the copper rods .
applying the voltage divider theorem
Vc = V x (
)
where
- Rc = resistance of copper =
(l = length , a = area, ρ = resistivity of copper)
- Ri = resistance of iron =
(l = length , a = area, ρ₀ = resistivity of copper)
Vc = V x (
)
Vc = V x (
)
Vc = V x (
)
where
- ρ = resistivity of copper = 1.72 x 10^{-8} ohm.meter
- ρ₀ = resistivity of iron = 9.71 x 10^{-8} ohm.meter
Vc = 16 x (
)
Vc = 2.41 v

Answer:
Both technicians are correct.
Explanation:
Printed circuits boards are copper layers attached to a dielectric plane with some design on it. This design is made to direction the current flow through a predefined path or electrical circuit. This way is easier to interconnect electronic devices instead of using cables for each connection.
Since the printed circuit board PCB its made of cooper, touching the printed circuit board may cause in the middle term corrosion and even rust, because the cooper in touch with the salt, sweat, and other stuff from the fingerprints can react in the metal surface, creating corrosion.
