A horizontal conductor that is part of a power line carries acurrent of 7200 A from south tonorth. Earth's magnetic field (60.0 µT) is directed towardthe north and is inclined downward at 70° to the horizontal. Find the magnitude anddirection of the magnetic force on 160 m of the conductor due to Earth's field.
Determine which of these properties hold or don't hold for the following discrete time systems. Justify your answers. IN each example, y(t) denotes the system output and x(t) denotes the system input.
trace how the electrons and holes move through the device under the two different biasing conditions. Explain how these three devices work in terms of holes and electrons.
An optical waveguide with gain and cleaved facets result in high reflection of the light wave resulting in oscillations which causes the guide to become a laser. What is the reflection coefficient of the wave in the guide at the cleaved interface
Earth-based 802.11a or 802.11g wireless LAN standards transmit data using a bandwidth of 16.56 MHz. What is the theoretical thermal noise level (in V) in an ideal receiver operating with an input impedance of 50 ohms
A current generated in the stack and a stack voltage of 6.0 V. As an engineer, you have a choice to install a recirculation pump to recycle the unused hydrogen from the anode exhaust back into the anode to increase the effective fuel utilization t..
