Voltage control method.<\/p>\n<p>Ward-Leonard control is a method of controlling the speed of a DC motor by varying the voltage applied to its armature. The voltage is controlled by a variable resistor, called a rheostat, which is placed in series with the armature. When the rheostat is adjusted, it changes the amount of current that flows through the armature, which in turn changes the speed of the motor.<\/p>\n<p>The other options are incorrect because they do not describe the Ward-Leonard control method.<\/p>\n<ul>\n<li>Option B, Field diverter method, is a method of controlling the speed of a DC motor by varying the amount of current that flows through the field winding. The field winding is a coil of wire that surrounds the stator of the motor. When the current through the field winding is increased, the magnetic field of the motor is increased, which in <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> turn increases the speed of the motor.<\/li>\n<li>Option C, Field control method, is a method of controlling the speed of a DC motor by varying the strength of the magnetic field produced by the field winding.
