Resistors In Series And Parallel Flashcards
What is the function of a resistor in a circuit?
Limits the current in a circuit
Resistors are essential components that control the flow of electric current.
What is the purpose of the practical experiment on resistors?
To find out what happens to the total resistance when resistors are put in series and in parallel
Understanding how resistors affect current and resistance is fundamental in physics.
What happens to the total resistance in a series circuit?
The total resistance is the same as both resistors added up
Adding resistors in series increases the total resistance.
What effect does adding more resistors in series have on current?
The current decreases
As resistance increases with each added resistor, the current flowing through the circuit decreases.
What happens to the total resistance in a parallel circuit?
The total resistance is less than the smallest resistor
Parallel circuits allow multiple paths for current, reducing overall resistance.
What effect does adding more resistors in parallel have on current?
The current increases
More paths for current flow lead to an increase in total current.
What is a reason why results in the experiment might not be completely accurate?
Meters aren’t completely accurate, power pack potential difference fluctuates, temperature of wires changes
These factors can affect the measurements taken during the experiment.
What is the resolution of measurements in the experiment?
0.01 resolution
Example measurements include values like 0.41A, 0.32A, 0.39A.
Fill in the blank: In a series circuit, adding a resistor results in _______.
more resistance and less current
This relationship is fundamental to understanding series circuits.
Fill in the blank: In a parallel circuit, each time you add more resistors, the total resistance _______.
decreases
This occurs due to the creation of additional pathways for current.
True or False: The total resistance in a parallel circuit is equal to the sum of all resistors.
False
The total resistance in a parallel circuit is always less than the smallest resistor.
