A high current consumption of the consumer increases the required capacity of the capacitor enormously. The half period $mathbf{Delta t}$ can be calculated from the frequency of the voltage. The formula is: $Delta t = frac{1}{2} cdot T$. At the mains voltage of 50 Hz we get $frac{1}{2} cdot frac{1}{50}$ with a result of $Delta t = 10ms$.
