A single-phase, full-bridge diode rectifier fed from a $230$ $\text{V}$, $50$ $\text{Hz}$ sinusoidal

source supplies a series combination of finite resistance, $\text{R}$, and a very large

inductance, $\text{L}$. The two most dominant frequency components in the source

current are:

1. $50\:Hz,\:0\:Hz$
2. $50\:Hz,\:100\:Hz$
3. $50\:Hz,\:150\:Hz$
4. $150\:Hz,\:250\:Hz$
