Physical Properties of Coil
Computes turns per winding, number of windings, coil diameter, cross-sectional area, wire length, resistance per metre, total resistance, voltage, and power for a coil wound on a cylindrical bobbin.
Inputs
Diameter of the winding wire in millimetres
Total number of turns in the coil
Winding length of the bobbin in millimetres
Inner diameter of the bobbin in millimetres
Rated current in amps
Results
⚠Wire diameter must be greater than zero
Turns per Winding—Number of turns that fit in one winding layer (bobbin length / wire diameter)
Number of Windings—Number of winding layers required to accommodate all turns
Coil Diameter—mmOuter diameter of the wound coil in millimetres
Cross Sectional Area—mm²Cross-sectional area of the wound coil in square millimetres
Total Length of Wire in Coil—mTotal wire length in the coil in metres
Resistance per Metre—Ω/mResistance per metre based on copper wire resistivity (reference diameter 0.812mm)
Resistance—ΩTotal DC resistance of the coil in ohms
Voltage at Rated Current—VVoltage across the coil at rated current in volts
Power at Rated Current—WPower dissipated at rated current in watts
