[amp_mcq option1=”0.5 Imax” option2=”0.707″ option3=”0.9″ option4=”1.414 Imax” correct=”option2″]<\/p>\n
The correct answer is B. 0.707 Imax.<\/p>\n
The root mean square (rms) value of a sine wave is the square root of the average of the squared values of the wave. In other words, it is the value of a constant DC current that would produce the same heating effect in a resistor as the sine wave.<\/p>\n
The rms value of a sine wave can be calculated using the following formula:<\/p>\n
$I_{rms} = \\frac{I_{peak}}{\\sqrt{2}}$<\/p>\n
where $I_{peak}$ is the peak value of the sine wave.<\/p>\n
Therefore, the rms value of a sine wave with peak value $I_{max}$ is $I_{rms} = \\frac{I_{max}}{\\sqrt{2}} = 0.707 I_{max}$.<\/p>\n
Option A is incorrect because it is the average value of a sine wave, not the rms value.<\/p>\n
Option C is incorrect because it is the peak value of a sine wave, not the rms value.<\/p>\n
Option D is incorrect because it is twice the rms value of a sine wave.<\/p>\n","protected":false},"excerpt":{"rendered":"
