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 8
A circuit contains three bulbs in parallel. If the current through each bulb is 0.5 A, what is the total current supplied by the battery?
A student builds a circuit with two bulbs in series and measures the brightness. She then builds a parallel circuit with the same bulbs. Which circuit will have brighter bulbs?
A student connects two bulbs in series to a battery. If one bulb burns out, what happens to the other bulb?
Describe one advantage and one disadvantage of using a series circuit.
Describe the main difference between a series and a parallel circuit.
Explain what happens to the total resistance in a parallel circuit as more branches are added.
Explain why household lights are connected in parallel and not in series.
If a 9 V battery is connected to a series circuit with three identical bulbs, what happens to the brightness of each bulb compared to a single bulb connected to the same battery?
In a parallel circuit, if more branches are added, what happens to the total current from the source?
Which type of circuit is safer for wiring in buildings and why?
A 24 V battery is connected to two resistors, R₁ = 8 Ω and R₂ = 12 Ω, in series. What is the voltage drop across R₂?
A circuit contains four resistors of 5 Ω, 10 Ω, 15 Ω, and 20 Ω connected in series to a 50 V battery. Calculate the total current flowing through the circuit.
A circuit has three resistors: 2 Ω and 4 Ω in series, and this combination is connected in parallel with a 6 Ω resistor. What is the total resistance of the circuit?
A student builds a circuit with a 9 V battery and two resistors, 3 Ω and 6 Ω, in parallel. Calculate the total current supplied by the battery.
A student connects three identical bulbs in parallel to a battery. If the total current from the battery is 3 A, what is the current through each bulb?
In a parallel circuit, if one branch contains a 4 Ω resistor and another branch contains a 12 Ω resistor, and both are connected to a 24 V battery, what is the current through the 12 Ω resistor?
