Question

1. which of the following best describes a secondary use of resistors in an electrical circuit?

a current divider

a current multiplier

a voltage divider

a voltage multiplier

Explanation:

Analyze the primary and secondary functions of resistors

While the primary purpose of a resistor is to limit or control the flow of electric current in a circuit, resistors are frequently configured in series to scale down voltages.

Evaluate the options

Using the Voltage Dividers knowledge point

• A current divider: Resistors in parallel can divide current, but this is typically considered a primary current-limiting behavior rather than a distinct secondary application like voltage scaling.
• A current multiplier: Resistors are passive components and cannot multiply current.
• A voltage divider: A series combination of resistors is widely used to create a specific output voltage that is a fraction of the input voltage. This is a fundamental secondary application.
• A voltage multiplier: Resistors cannot multiply voltage; this requires active components or capacitive networks.

Thus, a voltage divider is the best description of a secondary use.

Answer:

• A current divider
• A current multiplier
• A voltage divider (Correct answer)
• A voltage multiplier
