Test: Average and RMS Values of an Alternating Current - Question 1

Calculate the crest factor if the peak value of current is 10A and the rms value is 2A.

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 1

We know that:
Crest factor = Peak value/RMS value.
Substituting the values from the given question, we get crest factor = 5.

Test: Average and RMS Values of an Alternating Current - Question 2

For a rectangular wave, average current is ______ rms current.

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 2

The rms value is always greater than the average except for a rectangular wave, in which the heating effect remains constant so that the average and the rms values are the same.

Test: Average and RMS Values of an Alternating Current - Question 3

What is the effective value of current?

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 3

RMS current is also known as the effective current. RMS stands for Root Mean Square. This value of current is obtained by squaring all the current values, finding the average and then finding the square root.

Test: Average and RMS Values of an Alternating Current - Question 4

What is the type of current obtained by finding the square of the currents and then finding their average and then fining the square root?

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 4

RMS stands for Root Mean Square. This value of current is obtained by squaring all the current values, finding the average and then finding the square root.

Test: Average and RMS Values of an Alternating Current - Question 5

What is the current found by finding the current in an equidistant region and dividing by n?

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 5

The average value of the current is the sum of all the currents divided by the number of currents.

Test: Average and RMS Values of an Alternating Current - Question 6

Peak value divided by the rms value gives us?

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 6

Peak and crest factor both mean the same thing. Hence the peak value divided by the rms value gives us the peak or crest factor.

Test: Average and RMS Values of an Alternating Current - Question 7

In a sinusoidal wave, average current is always _______ rms current.

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 7

The average value of current is the sum of all the currents divided by the number of currents whereas RMS current is obtained by squaring all the current values, finding the average and then finding the square root. Hence RMS current is greater than average current.

Test: Average and RMS Values of an Alternating Current - Question 8

__________ current is found by dividing the area enclosed by the half cycle by the length of the base of the half cycle.

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 8

The average value of current is the sum of all the currents divided by the number of currents. Hence it can also be found by dividing the area enclosed by the half cycle by the length of the base of the half cycle.

Test: Average and RMS Values of an Alternating Current - Question 9

RMS stands for ________

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 9

RMS stands for Root Mean Square. This value of current is obtained by squaring all the current values, finding the average and then finding the square root.

Test: Average and RMS Values of an Alternating Current - Question 10

Find the average value of current when the current that are equidistant are 4A, 5A and 6A.

Detailed Solution for Test: Average and RMS Values of an Alternating Current - Question 10

The average value of current is the sum of all the currents divided by the number of currents. Therefore average current = (5 + 4 + 6)/3 = 5A.
