Irms2=(∫0T [I(t)]2dt)/TThe Attempt at a Solution
: I tried to integrate but I'm getting a T term.
I don't know how to type it...can I post a picture?SammyS said:What result do you get for the integration ?
Yes, if it's readable.randomgamernerd said:I don't know how to type it...can I post a picture?
An AC (alternating current) circuit is a type of electrical circuit in which the current periodically changes direction. This is in contrast to a DC (direct current) circuit where the current flows in one direction only.
RMS (Root Mean Square) current is a measure of the effective current in an AC circuit. It is calculated by taking the square root of the mean (average) of the squared values of the current over one cycle. This is different from the average current which is simply the average of the values of the current over one cycle.
The formula for calculating RMS current in an AC circuit is: RMS current = (peak current / √2).
To find the peak current in an AC circuit, you can use a multimeter or an oscilloscope to measure the maximum value of the current over one cycle. Alternatively, if you know the voltage and resistance in the circuit, you can use Ohm's law (I = V/R) to calculate the peak current.
Calculating the RMS current in an AC circuit is important because it gives a more accurate measure of the actual current flowing in the circuit. This is especially important when dealing with high voltage circuits, as the peak current may be significantly higher than the RMS current, and can cause damage to components if not properly accounted for.
