A coil consists of 200 turns of copper wire and have a cross-sectional area of 0.8 mmm square. The mean length per turn is 80 cm and the resistivity of copper is 0.02μΩm at normal working temperature. Calculate the resistance of the coil

The resistance of the coil is 4 Ω.

Explanation:

The resistance (R) of the coil can be calculated using the following equation:

Where:

ρ: is the resistivity of copper = 0.02x10⁻⁶ Ωm

L: is the length of the coil

A: is the cross-sectional area = 0.8 mm² = 8x10⁻⁷ m²

The length of the coil is given by:

Now, the resistance is:          

Therefore, the resistance of the coil is 4 Ω.
