What is 75% output on a 4-20 milliamp transmitter?

Explanation:
To determine what 75% output corresponds to on a 4-20 milliamp (mA) transmitter, it is important to first understand the output range of a 4-20 mA signal. The minimum output (0% level) is 4 mA, and the maximum output (100% level) is 20 mA. To calculate 75% output within this range, you first need to determine the full range of mA output, which is: 20 mA - 4 mA = 16 mA This result represents the full range of output from 0% to 100%. Next, to find the value that represents 75% of this range, you can calculate: 75% of the 16 mA range is: 0.75 * 16 mA = 12 mA Now, since 12 mA is the increase from the minimum output of 4 mA, you add this value to the minimum output: 4 mA + 12 mA = 16 mA Therefore, 75% output on a 4-20 milliamp transmitter corresponds to 16 milliamps. This calculation confirms that the correct answer is indeed 16 mill

To calculate 75% output within this range, you first need to determine the full range of mA output, which is:

20 mA - 4 mA = 16 mA

This result represents the full range of output from 0% to 100%. Next, to find the value that represents 75% of this range, you can calculate:

75% of the 16 mA range is:

0.75 * 16 mA = 12 mA

Now, since 12 mA is the increase from the minimum output of 4 mA, you add this value to the minimum output:

4 mA + 12 mA = 16 mA

Therefore, 75% output on a 4-20 milliamp transmitter corresponds to 16 milliamps. This calculation confirms that the correct answer is indeed 16 mill
