To solve the problem step by step, we will find the peak value of current, the mean value of current over half a cycle, and the value of current at a specific time after it was zero. ### Step 1: Find the Peak Value of Current (I₀) The effective value of current (I_RMS) is given as 5.0 A. The relationship between the effective value (RMS) and the peak value (I₀) is given by the formula: \[ I₀ = I_{RMS} \times \sqrt{2} \] ...
