In a parallel circuit containing several identical resistors, how does the total or equivalent resistance compare to an individual resistor?
It is less than one individual resistor's resistance.
It changes depending on each resistor’s power rating.
It is more than one individual resistor's resistance.
It is equal to one individual resistor's resistance.
If you double the voltage across a resistor, while the resistance stays the same, by how much does the current through it change?
There is no change in current.
It halves.
It quadruples.
It doubles.
If resistors are connected end-to-end with no branching paths, they are said to be arranged in what way?
Series
Composite
Parallel
Network
In a series circuit with identical resistors, how do you find the equivalent resistance?
Multiply one individual resistance by itself.
Divide the total voltage by the number of resistors.
Use only the highest value of resistance.
Add all individual resistances together.

Total current increases as more resistors are added.
Total current becomes zero once any additional resistor is added.
Total current decreases as more resistors are added.
