Question

A motors draws 2.1 A of current when running at full speed and connected to a 120 Volt line. Suppose the
same motor is connected to a 220 Volt power source and as the result it runs 1.4 times faster than its full
speed and draws 10 A. What is the armature resistance of the motor?

Answer 2

Answer:

22 ohms is the Resistance.

Explanation:

Given,

Electric Current = 10 A

Potential Difference = 220 V

Resistance = Potential Difference/Electric Current

= (220/10) ohms

= 22 ohms

Hope this helps.
