Potential divider Flashcards
(10 cards)
What is a potential (voltage) divider?
A circuit that splits the input voltage into smaller output voltages using two or more resistors.
What is the main purpose of a potential divider?
To provide a specific, controlled voltage output less than the input voltage.
How does a potential divider control voltage?
By varying the resistance values, the voltage across each resistor can be adjusted.
What components are typically used in a potential divider?
Two or more resistors connected in series.
In a potential divider, where is the output voltage taken from?
Across one of the resistors in the series.
Why are potential dividers useful in electronic circuits?
They provide adjustable voltages to sensors, LEDs, or other components.
Can you draw a simple potential divider circuit?
Yes; it consists of a voltage source connected in series with two resistors, and the output voltage is taken between the resistors.
What does changing the resistor values in a potential divider affect?
It changes the ratio of output voltage to input voltage.
How would you identify a potential divider in a circuit diagram?
Look for two or more resistors in series with an output connection between them.
Is a potential divider the same as a voltage regulator?
No; a potential divider provides a fixed division of voltage, while a regulator maintains constant voltage despite load changes.
