Parrallel and series circuts Flashcards
(20 cards)
What is a series circuit?
A series circuit is a circuit in which the components are connected end-to-end, so that the current flows through each component in turn.
True or False: In a series circuit, if one component fails, the entire circuit stops working.
True
What is a parallel circuit?
A parallel circuit is a circuit where the components are connected across common points or junctions, allowing multiple paths for current to flow.
Fill in the blank: In a parallel circuit, the voltage across each component is _____ the same.
always
How is the total resistance calculated in a series circuit?
The total resistance in a series circuit is the sum of the individual resistances.
What happens to the total current in a parallel circuit as more branches are added?
The total current increases as more branches are added.
True or False: In a series circuit, the current is the same through all components.
True
What is the formula for calculating total resistance in a parallel circuit?
1/R_total = 1/R1 + 1/R2 + 1/R3 + …
Multiple Choice: In which type of circuit can you have multiple paths for current flow? A) Series B) Parallel C) Both
B) Parallel
What is the effect of adding more resistors in series on the total resistance?
Adding more resistors in series increases the total resistance.
Fill in the blank: The total voltage in a series circuit is _____ to the sum of the voltages across each component.
equal
True or False: In a parallel circuit, if one branch fails, the other branches will still function.
True
What is the relationship between voltage and current in a parallel circuit?
Voltage is the same across all components, while current can vary.
Multiple Choice: Which circuit type is more commonly used in household wiring? A) Series B) Parallel C) Neither
B) Parallel
How does the total current in a series circuit compare to the current through each component?
The total current is the same as the current through each component.
What happens to the total voltage in a parallel circuit when more branches are added?
The total voltage remains the same.
Fill in the blank: In a series circuit, the total voltage is _____ to the sum of the individual voltages.
equal
True or False: In a series circuit, the total current is equal to the sum of the currents through each component.
False
What happens to the total resistance in a parallel circuit as more resistors are added?
The total resistance decreases.
What is a common application of series circuits?
Series circuits are commonly used in string lights.
