The coil of the electric heater (220V) is made of fechral wiring with a length of 33.7 mm ^ 2 and a cross-sectional area of 0.9 mm ^ 2. Determine the resistance of the conductor.
L = 33.7 m.
S = 0.9 mm2.
ρ = 1.3 Ohm * mm2 / m.
R -?
R = ρ * L / S.
R = 1.3 Ohm * mm2 / m * 33.7 m / 0.9 mm2 = 48.7 Ohm.
Answer: R = 48.7 ohms.
