Voltage Divider Rules Quiz
easy
5 Questions
Question 1 of 5
In a series circuit, the voltage across a resistor is directly proportional to:
Voltage divider rule utilizes the proportion of the resistance to calculate voltage drop.
Question 2 of 5
What is the formula to calculate the voltage across a resistor (R1) in a series circuit with two resistors (R1 and R2) and a total voltage (Vtotal)?
The voltage across a resistor is proportional to its resistance relative to the total resistance.
Question 3 of 5
If two resistors of 10 ohms and 20 ohms are connected in series with a 12V source, what is the voltage across the 10-ohm resistor?
V1 = 12V * (10 ohms / (10 ohms + 20 ohms)) = 4V
Question 4 of 5
The voltage divider rule is primarily used for:
The primary purpose is to calculate voltage drops across components.
Question 5 of 5
Which of the following is NOT a requirement for applying the voltage divider rule?
The resistor values don't have to be equal for the rule to apply, but they do have to be in series.
