A full-wave rectifier uses two diodes, a center-tapped transformer, a capacitor ($C$), and a load resistance ($R_L$). If the rectified output has significant ripple, increasing the value of which component would most effectively reduce it?

The potential in depletion layer is due to

Which one of the following statements is not correct

A half-wave rectifier is used to convert an AC signal to a pulsating DC signal. The input signal has a frequency of $f$. What is the frequency of the pulsating DC output?

A $p - n\;$ photodiode is made of a material with a band gap of 2.0 eV. The minimum frequency of the radiation that can be absorbed by the material is nearly

A zener diode is used for

The current in a triode at anode potential $100\;V$ and grid potential $- 1.2\;V$ is $7.5\;mA$. If grid potential is changed to $- 2.2\;V,$ the current becomes $5.5\;mA.$ the value of trans conductance $\left( {{g_m}} \right)$ will be
