Choose the Incorrect statement for the half-wave rectifier out of the following statements:

1. The maximum theoretical efficiency is \(40.6\%\).
2. A DC-ammeter connected to the output of the rectifier reads \(I_0\over \pi\) current where \(I_0\) is the peak value of current in the circuit.
3. An AC-ammeter connected to the output of the rectifier reads \(\frac{I_0}{\sqrt{2}}\) current where \(I_0\) is the peak value of current in the circuit.
4. Ripple factor is greater than one.
