Now if the load on the motor is increased, the power factor will decrease and the armature current will increase.<\/p>\n<p>When the load on a synchronous motor is increased, the motor will draw more current to maintain the same speed. This increased current will cause the power factor to decrease. The armature current will also increase because the motor is working harder to overcome the increased load.<\/p>\n<p>The power factor is a measure of how efficiently a motor is converting electrical energy into mechanical energy. A power factor of 1 indicates that the motor is 100% efficient, while a power factor of 0 indicates that the motor is not converting any electrical energy into mechanical energy.<\/p>\n<p>The armature current is the current that flows through the armature winding of a motor. The armature current is proportional to the torque that the motor is producing.<\/p>\n<p>When the load on a synchronous motor is increased, the motor will draw more current to maintain the same speed. This increased current will cause the power factor to decrease. The armature current will also increase because the motor is working harder to overcome the increased load.<\/p>\n<p>The following is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: Power factor as well as armature current will decrease. This is not the correct answer because the power factor will decrease but the armature current will increase.<\/li>\n<li>Option B: Power factor as well as armature current will increase. This is not the correct answer because the power factor will decrease but the armature current will increase.<\/li>\n<li>Option C: Power factor will increase but armature current will decrease.
