When effective value of current is 10 What is its peak value?

The peak value of alternating current is 14.1 Ampere in a circuit where RMS value of current is 10 Ampere. So, option A is correct.

How do you calculate RMS current from peak current?

For example, when the AC waveform is an ideal sine wave, the relationship between RMS and Peak Current is as follows: RMS Current = Peak Current x 0.707 or Peak Current = RMS Current x 1.414.

What is the RMS value of AC current?

The RMS value of AC current is equal to that amount of DC current which produces the same heating effect flowing through the same resistance for the same time. It is the actual value of an alternating quantity that tells us the energy transfer capability of an AC source.

What is the effective value of current?

The effective value or the rms value of the current in the full time period can be found by integrating the current in the time period $0 < t < T$. So we can find the rms value by integrating the current over the small limits in time period.

What is the frequency of AC mains in India?

India and most European countries use the electricity which has the frequency of AC mains as 50Hz.

What is peak value of alternating current?

The peak value of alternating current is √2 times the root mean square value of the alternating current. where P signifies the power dissipated, I represents the value of current flowing through the resistance having value R.

How do you calculate peak-to-peak value?

RMS Voltage to Peak-to-Peak Voltage Formula Using RMS voltage, the peak voltage can be found using this formula where VRMS is RMS voltage. So, peak-to-peak voltage is equal to two times the square root of two times RMS voltage.

What is the peak value of alternating current?

What is peak value of AC?

Peak and R.M.S Value Of An Alternating Current / Voltage. The maximum value reached by an alternating quantity in one cycle is known as the peak value.

Why is the peak value of an alternating current never used?

In specifying an alternating voltage or current, its peak or maximum value is rarely used because it has that value only twice each cycle. Furthermore, the average or mean value cannot be used because it is positive as much as it is negative, so the average value is zero.

How do you find the peak value of an alternating quantity?

Peak Value: V P or V MAX. The maximum value, positive or negative, of an alternating quantity (such as voltage or current) is known as its amplitude of the waveform, max value or peak value. Its denoted by V P, I P or E MAX and I MAX. V P = √2 x V RMS.

What is the peak value of a voltage?

Peak Value: V P or V MAX. The maximum value, positive or negative, of an alternating quantity (such as voltage or current) is known as its amplitude of the waveform, max value or peak value. Its denoted by V P, I P or E MAX and I MAX.

What is the mean value of alternating current for completing cycle?

The mean value of alternating current for completing the full cycle will be zero. RMS stands for Root-Mean-Square of instantaneous current values. The RMS value of alternating current is given by direct current which flows through a resistance. The RMS value of AC is greater than the average value.
