To find the effective value of the current given by the equation \( i = 2 + 4 \cos(100 \pi t) \), we will follow these steps: ### Step 1: Identify the DC and AC components The current \( i \) can be separated into its DC and AC components: - The DC component \( I_{DC} \) is the constant term, which is \( 2 \) A. - The AC component \( I_{AC} \) is the term that varies with time, which is \( 4 \cos(100 \pi t) \). ### Step 2: Calculate the RMS value of the AC component ...
