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
. The mean length per turn is 80cm and the resistivity of copper is 0.02
–m. Find the resistance of the coil and power absorbed by the coil when connected across 110 V d.c. supply
