Question
Chapter 45, Problem 1SQ
To determine
Explain why small DC motors can be connected directly across the line for starting.
Expert Solution & Answer

Explanation of Solution
Small DC motors can be started by connecting directly across the line with the help of a switch or a connector. It does not cause any damage because the motor can attain full speed very quickly due to small amount of rotor’s inertia and friction. Also a high starting current will decrease very quickly due to the fast increase in the counter-electromotive force.
Conclusion:
Thus, a motor that can be connected directly across a line for starting is explained.
