A.C. quantities are always expressed in root-mean-square(r.m.s.) values, unless otherwise stated. For sinsoidal waveform, this equates to 0.707 times the peak value. For example, an AC current with an amplitude of 100 A has an r.m.s. value of 70.7 A.
An a.c. current expressed as an r.m.s. value will do exactly the same amount of work as a d.c. current of the same value. In other words, a 50 A (r.m.s.) a.c. current will do exactly the same amount of work as 50 A d.c. This is why r.m.s. values are also referred to as 'effective values' of a.c..
What else can I help you with?
An AC has a peak value of 12 amps what is the average value of the current?
i think average value of current in ac current is zero.
How do you find effective value of a current?
The effective value of an AC = AC/√2. Example: the effective value of 8.5 V AC is 6.01 V, because 8.5/√2=6.01 Hope that helped :)
What is the virtual value of ac whose peak value is 707V?
virtual value=peak value/root 2 =707/1.414 =500
What mathematical formulas is used to find the average value voltage for an ac voltage?
The RMS value of an AC voltage is VRMS = VPEAK / sqrt(2), where VPEAK = the voltage peak to neutral.AnswerThe average value of a sinusoidal a.c. voltage is zero.
What is the maximum absolute value reached by a voltage or current waveform?
define the maximum value of an ac wave form

How do you change dc values to ac values?
To convert DC values to AC values if you are wanting RMS values they are the same. 100V DC and 100V AC (RMS) are the same "value". If you want to know the Peak-To-Peak AC value you would multiply the RMS value by 1.414. So 100V AC RMS equals 141.4 V Peak to Peak.
What is the effective value of an AC signal of 141 volts peak value?
If the AC signal is sinusoidal, then the RMS value is 141 divided by square root of 2, i.e. 99.7 volts.
What is the instantaneous value of AC?
The instantaneous value of an alternating current (AC) is the value of the current at a specific moment in time. It is constantly changing direction and magnitude due to its alternating nature, so the instantaneous value represents its value at that precise instant.
Why you are calculating average and rms values for ac supply?
We will always calculate rms value only since the average value of ac current or voltage is zero. So we are using rms values in the ac circuit to calculate the power and to solve an ac circuit.
What is the average value of the alternating current (AC) in the circuit?
The average value of the alternating current (AC) in the circuit is calculated by finding the root mean square (RMS) value of the current waveform. This value represents the equivalent direct current that would produce the same amount of power dissipation in a resistor as the AC current.
Does a volt meter read rms?
Yes, if it is set to measure AC, it is usually calibrated to RMS.
Bc equals 1 what is the value of ac?
\3
What is an AC source?
signal value changes with time
How does the maximum value of the current depend on the frequency of the AC voltage source?
The maximum value of the current in an AC circuit depends on the frequency of the voltage source. As the frequency increases, the maximum current value also increases.
When performing an AC analysis on a circuit which value of AC current should we use?
For calculations Peak or magnitude is used.
