SUMMARY
Calculating the resistance of a coil can be achieved without directly measuring amperage by utilizing the coil's physical properties. Key factors include the coil's diameter, the number of turns, and the material type, which influence its resistivity. The resistivity can be calculated using the formula R = ρ(L/A), where R is resistance, ρ is resistivity, L is the length of the wire, and A is the cross-sectional area. This method allows for accurate resistance calculations based solely on the coil's specifications.
