Why build your own DC generator MCQ set

Ready-made DC generator MCQ PDF sets tend to follow a textbook order, which rarely matches the derivations, sign conventions and diagrams your instructor used in class. Questions generated from your own lecture notes stay closer to the wording and coverage you will see on the exam.

  • Cover armature reaction, commutation and EMF equations from your own notes
  • Mix multiple-choice with true/false and short answer items
  • Read an explanation for each answer, including why the distractors are wrong
  • Study in the browser on the free plan, or export files on a paid plan
Example Pythagorean theorem practice questions
A right triangle has legs of 3 cm and 4 cm. What is the hypotenuse?5 cm. Because 3² + 4² = 9 + 16 = 25, the hypotenuse is √25 = 5.
In a right triangle, the hypotenuse is 13 and one leg is 5. What is the other leg?12. Because 5² + b² = 13², b² = 169 − 25 = 144, so b = 12.
True or false: the Pythagorean theorem applies to any triangle.False. It applies only to right triangles, where a² + b² = c² uses the hypotenuse c.
Which side is the hypotenuse in a right triangle?The side opposite the right angle, which is always the longest side. It is the c in a² + b² = c².
A 10 m ladder leans against a wall with its base 6 m from the wall. How high does it reach?8 m. Because 6² + h² = 10², h² = 64, so h = 8.

Frequently asked questions

How do I tell which side is the hypotenuse?

The hypotenuse is the side opposite the right angle and is always the longest side. Label it c before you substitute into a² + b² = c².

How should I practice Pythagorean theorem questions?

Work problems where you solve for different unknowns, such as a leg or the hypotenuse. Check each answer by plugging it back into the equation.

Can I export generated questions to PDF?

PDF and DOCX export are included on the Plus plan, and QTI 2.1 and Moodle XML export are on Pro.

Do I need a credit card to start?

No. The free plan includes 3 generations per month and browser study, and it does not require a credit card.
