An ac source (sinusoidal source with frequency 50 Hz ) is connected in series with a rectifying diode, a 100 resistor, a 1000 ~F capacitor and a milliammeter. After some time the mThe fundamental frequency of the output of a bridge rectifier driven by ac mains isWhich one of the following devices does not respond to the intensity of light incident on it?A simple laboratory power supply consists of a transformer, bridge rectifier and a filter capacitor. It drives a suitable load. If due to some reason one of the diodes in the rectiMagnified, erect and virtualIn a photodiode the reverse current increases when exposed to light of wavelength 620 nm or less. The band gap of the semiconductor used isThe adjacent figure shows I - V characteristics of a silicon diode. In this connection three statements are made - (I) the region OC corresponds to reverse bias of the diode, (II) In the network shown below the voltage V₀ is nearly Full Semiconductors list All Olympiad workbook PYQs
