Respuesta :
the current in the coil of the motor is 8.70A
The motor coil's resistance is R = 27.
The motor's working voltage is V o = 235 V.
When the motor is running at its top speed, the rear emf is V b =141V.
The initial coil current when the motor is turned on must be calculated.
using the information provided,
I=VoR=(235v/27Ω)=8.70A
The number of turns is the first element that affects the current coil's strength. The current in amperes increases with the number of revolutions. The number of turns in a coil also multiplies the magnetic field. The strength of the current of the coil passing through the conductor is the second crucial element.
