Current drawn by the armature of a D.C. motor is directly proportional to
Understand the Problem
The question is asking about the relationship between the current drawn by the armature of a D.C. motor and other variables that influence it. This could relate to concepts such as supply voltage, load torque, or armature resistance.
Answer
The torque required.
The current drawn by the armature of a DC motor is directly proportional to the torque required.
Answer for screen readers
The current drawn by the armature of a DC motor is directly proportional to the torque required.
More Information
In a DC motor, the armature current is affected by the load requirements. If more torque is needed to overcome a load, the motor will draw more current.
Tips
A common mistake is confusing the relationship between torque and speed with direct proportionality to current. Greater load increases torque, thus increasing current drawn.
