Overview
I’m trying to study for my Engineering course and I need some help to understand this question.
A coil consists of 2000 turns of copper wire hav-ing a cross-sectional area of 0.8 mm
2
. The mean length per turn is 80cm and the resistivity of copper is 0.02
μ
Ω
–m. Find the resistance of the coil and power absorbed by the coil when connected across 110 V d.c. supply
