P4.6 Parallel circuits Flashcards
What is the definition of a parallel circuit?
A parallel circuit is an electrical circuit where the components are connected across common points or junctions, providing multiple paths for current to flow.
True or False: In a parallel circuit, the total current is the sum of the currents through each branch.
True
Fill in the blank: In a parallel circuit, the voltage across each component is ______.
the same
What happens to the total resistance in a parallel circuit as more branches are added?
The total resistance decreases.
Calculate the total resistance for three resistors in parallel: R1 = 4Ω, R2 = 6Ω, R3 = 12Ω. What is the total resistance?
The total resistance is 2Ω.
What is the formula to calculate the total resistance (R_total) in a parallel circuit with two resistors (R1 and R2)?
1/R_total = 1/R1 + 1/R2
In a parallel circuit, if one branch fails, what happens to the other branches?
The other branches continue to function normally.
Multiple Choice: Which of the following statements is true about parallel circuits? A) Current is the same in all branches B) Voltage is the same in all branches C) Total resistance increases with more branches D) All of the above
B) Voltage is the same in all branches
Short Answer: Name one practical application of parallel circuits.
Household wiring systems.
True or False: In a parallel circuit, removing one component will stop the flow of current in the entire circuit.
False
