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. |
