Question 1 of 27070

Electric starting motors for diesel engines require high current for their operation. As a result of this, they __________.

🔍 Key Concepts

• Starting current vs running current in electric motors • Characteristics of series vs shunt DC motors • What a motor must tolerate when cranking a diesel engine

💭 Think About

• Which DC motor construction is typically used where very high starting torque and current are needed, such as cranking an engine? • When a motor briefly draws very high current at start, what must its mechanical and electrical design be able to withstand? • Look at each option and ask: does this describe a consequence of needing high current, or is it describing something unrelated?

✅ Before You Answer

• For each choice, ask: does this directly follow from the fact that the starting current is very high? • Recall which type of DC motor is known for high starting torque and current (series vs shunt). • Think about whether engine starters are expected to handle a short-duration overload safely or to run continuously at that level.
