The incoming solar radiation at a place on the surface of the earth is 1.2 KW/m².The amplitude of the electric field corresponding to this incident power is nearly equal to

In a junction diode

The transfer function of simple RC network functioning as a controller is $$$G\,{}_c\left( s \right)\,\,\,\,{{s + {z_1}} \over {s + {p_1}}}$$$

The condition for the RC network to act as a phase lead controller is

The resonant frequency of this series circuit shown in figure is
