The boiler is connected to a 220V network. What is the current strength in the coil of an electric boiler if it is made of nichrome wire 5 m long and a cross-sectional area of 0.1 mm2?

Given:
ρ = 1.1 Ohm * mm2 / m
l = 5 m
S = 0.1 mm2
U = 220V
Find Y =?
Decision:
Y = U / R
R = ρ * l / S
R = 1.1 Ohm * mm2 / m * 5 m / 0.1 mm2 = 55 Ohm
Y = 220 V / 55 Ohm = 4 A
Answer: Y = 4 A
