How does adding more resistors in parallel affect the total resistance?
It decreases the total resistance.
What is the formula for total resistance in a parallel circuit?
1/R_total = 1/R_1 + 1/R_2 + 1/R_3 + … + 1/R_n
True or False: In a parallel circuit, if one component fails, the remaining components continue to operate.
True

What happens to the total resistance if three identical resistors are connected in parallel?
The total resistance is one-third of the resistance of one resistor.
Which component’s failure does NOT affect the rest of the circuit in a parallel configuration?
Any individual component.
True or False: The current through each branch in a parallel circuit can be different.
True
What does a higher total current indicate in a parallel circuit?
It indicates lower total resistance.

True or False: In a parallel circuit, the total power consumed is the sum of the power consumed by each branch.
True
What is the relationship between current and resistance in a parallel circuit?
As resistance decreases, current increases.
What type of circuit allows for multiple paths for current to flow?
Parallel circuit
Multiple choice: Which is NOT a characteristic of parallel circuits? A) Same voltage across components B) Total current divides among branches C) Total resistance increases with more components
C) Total resistance increases with more components
How does the failure of one branch in a parallel circuit affect the overall circuit?
It does not affect the overall circuit; other branches continue to operate.
