Question

Resistor Color codes were developed by:

• A. Radio Manufacturers Association (RMA)
• B. International Organization for Standardization (ISO)
• C. Electronics Industries Alliance (EIA)
• D. a \& b are correct

Hint:

The resistor color code system helps quickly identify resistor values, with each color representing a specific digit.

Answer 1

The Correct Option is D

Step 1: Understand resistor color codes.
Resistor color codes are used to indicate the value and tolerance of resistors.
These codes were originally developed to standardize the identification process.
Step 2: Identify the organizations involved.
Both the Radio Manufacturers Association (RMA) and the International Organization for Standardization (ISO) were involved in developing resistor color codes.
The EIA also contributed, but the key organizations are RMA and ISO.
