The instantaneous current from an AC source is I = 6 sin (314 t ) ampere. What are the half cycle average and rms values of the current ?

Text Solution

AI Generated Solution

To solve the problem, we need to find the half cycle average and RMS values of the instantaneous current given by the equation: \[ I(t) = 6 \sin(314t) \, \text{A} \] ### Step 1: Identify the Peak Current (I₀) From the given equation, we can identify the peak current \( I_0 \): \[ I_0 = 6 \, \text{A} \] ...
