Irms=Imax/sqrt(2), it is only true if the input current is sinusoidal.

Can someone tell me the difference between rms & Max value?

Rajesh said:   9 years ago
Is 100 mA R.M.S value or Max. value?

Thanks for explaining the solution.

Irms = 0.707 im.

= 0.707*200.

= 141.4.

Irms = 0.707 im.

= 0.707*200.

= 141.4.

i1 = 100 mA, i2 = 100/_90 deg mA or 100j.

So adding it under root (square of 100 + square of 100) = 141.41 mA.

Let,I1=100ma through resistive & I2=100 through capacitive.

Therefore,

Total I=i1+i2 = 200A

RMS value = im/sqrt2 = 200/sqrt2 = 141 mA

sqrt(100^2 + 100^2)
