The starting winding is connected to a capacitor, which creates a magnetic field that helps the motor start. Once the motor is up to speed, the starting winding is disconnected.<\/p>\n<p>If the capacitor is replaced by a resistance, the magnetic field will not be created, and the motor will not start. If the motor is already running, it will continue to run, but it will run in reverse direction.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li><strong>A. torque will increase<\/strong>. This is not correct because the capacitor provides the magnetic field that creates the torque. Without the capacitor, there will be no torque and the motor will not start.<\/li>\n<li><strong>B. the motor will consume less power<\/strong>. This is not correct because the resistance will dissipate power, which will cause the motor to consume more power.<\/li>\n<li><strong>C. motor will run in reverse direction<\/strong>. This is the correct answer because the capacitor creates a magnetic field that causes the motor to rotate in one direction. Without the capacitor, the motor will rotate in the opposite direction.<\/li>\n<li><strong>D. motor will continue to run in same direction<\/strong>. This is not correct because the capacitor provides the magnetic field that causes the motor to rotate in one direction.
