the largest telescope in the world has an aperture of 10 m. According to the fresnel distance this makes ray optics valid for it, for a wavelength of lightsay 500 nm, uptil a distance of 2 * 10^7 m. I have read that after the fresnel distance, diffraction tends to dominate. But telescopes tend...
lets consider the wire connected to diode A and the wire connected to the load resistor B. When forward bias occurs then current flows through A and B. A due to the diode has an output current in the form of pulses. But B has no diode therefore the current would be ac through it. Both of...
but when the circuit is complete the diode wire has a pulsating current while the other wire has an ac current. Wouldnt that make things messy at the load resistor
