Series and Parallel Circuits starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Series and Parallel Circuits.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Describe the effect on total resistance if more resistors are added in parallel to a circuit.
Describe what happens to the brightness of bulbs in a series circuit if more bulbs are added.
Explain the difference between series and parallel circuits in terms of current and voltage distribution.
Explain why household electrical wiring is done in parallel rather than in series.
If three identical bulbs are connected in series to a battery, and one bulb burns out, what happens to the other bulbs?

Which of the following is a disadvantage of series circuits for lighting? (1) All lights receive full voltage (2) If one bulb fails, others remain lit (3) If one bulb fails, all go out (4) Each bulb can be controlled independently
In a parallel circuit, the total resistance is always _______ than the smallest individual resistance.
In a parallel circuit, the voltage across each branch is _______.
In a parallel circuit, if one branch is disconnected, do the other branches continue to work? Yes or No.
True or False: In a parallel circuit, the total current is equal to the sum of the currents through each branch.
True or False: In a series circuit, if one component fails, the entire circuit stops working.
True or False: The total resistance in a series circuit is always greater than the largest individual resistance.
