Question

1. which of the following fixed resistor types is constructed by using a carbon graphite compound and a resin-bonding material?

metal-film resistor

composition carbon resistor

carbon-film resistor

wire-wound resistor

Explanation:

Analyze the construction materials

Using the Resistor Applications knowledge point

• Carbon composition resistors (often called composition carbon resistors) are made from a mixture of finely powdered carbon graphite and a non-conductive resin-bonding material.
• The ratio of carbon to the binder determines the resistance value.

Compare with other resistor types

• Metal-film resistors are constructed by depositing a thin metal layer onto a ceramic substrate.
• Carbon-film resistors are made by depositing a thin carbon film onto an insulating ceramic rod.
• Wire-wound resistors are made by winding a resistive wire around a ceramic core.
• Therefore, the composition carbon resistor is the correct match.

Answer:

• Metal-film resistor
• Composition carbon resistor (Correct answer)
• (C) Carbon-film resistor
• (D) Wire-wound resistor
