Answer to Question #245850 in Electrical Engineering for Alock kumar

Question

The average value of an oscillating electric current over one period may be zero. For example, 2nt suppose that the current is described by a simple sinusoid: i(t) = sin 2πt/T where T is the period.

The average value of this function can be determined by the following equation:

i=∫ν0^T(2πt/T)dt/T-0 = -cos(2π) + cos0/T=0

Despite the fact that the net result is zero, such current is capable of performing work and generating heat . Therefore, electrical engineers often characterize such current by

I RMS = √1\T∫ν0^Ti^2(t)dt

where i(t) = the instantaneous current. Calculate the RMS or root-mean-square current of the waveform shown in following figure using the trapezoidal rule, Simpson's 1/3 rule, Simpson's 3/8 rule for T =1 s taking n = 6.
