Why a custom quiz beats a generic printable one

If you were hoping for a ready-made printable quiz, a free quiz maker for PDFs works better when it builds the questions from your own material. A worksheet written for a generic textbook rarely matches the chapter your instructor assigned, so the questions can miss what will actually be tested.

Questions are built from the file you upload, so the quiz matches your course.
Multiple choice, true/false and short answer questions are available.
Every question comes with an explanation of the correct answer.
The free plan includes 3 generations per month and browser study, with no credit card needed.

Example electric circuits quiz questions

What is the unit of electrical resistance?The ohm (Ω). Resistance is measured in ohms, named after Georg Ohm.

In a series circuit, what happens to the current when you add another resistor?It decreases. Adding resistance in series raises the total resistance, and with the voltage fixed, Ohm's law gives a lower current.

True or false: in a parallel circuit, every branch has the same voltage as the source.True. Each branch connects across the same two points, so each one sees the source voltage.

What does closing a switch do in a circuit?It completes the loop so current can flow. The closed switch makes a continuous conductive path.

What is the formula for electrical power in terms of voltage and current?P = V × I. Power equals voltage times current, and the forms P = I²R and P = V²/R come from Ohm's law.

Frequently asked questions

How many questions should a practice quiz on electric circuits include?

Ten to twenty questions usually cover one chapter well and are quick to finish in one sitting. Retaking a shorter quiz several times often helps more than doing one very long quiz.

What should I check first when I get a circuits question wrong?

Look at the explanation, then redraw the circuit and apply Ohm's law or the series and parallel rules to the numbers in the question. Writing out the steps shows where your reasoning went off.

Can I export my quiz to PDF for free?

No. Exports are part of the paid plans, and PDF, DOCX, Anki and CSV export are included in Plus. The free plan lets you study the quiz in the browser with 3 generations per month.

Do I need a credit card to start?

No. You can start on the free plan without a credit card, and students get 40% off Plus with a school email.
