A single-phase diode bridge is supplied by an ac source of 257 V, 60 Hz. This bridge in turn supplies a dc load of Idc= 60 A.
Estimate the voltage drops due to (1) source with an inductance of 0.02 mH, (2) each diode with forward voltage drop of ΔVf = 0.6 + 0.0015 Idc, and (3) source and wiring resistances of Rr = 0.0015 Ω.
Draw an equivalent circuit to represent such rectifier.
Research the circuit topologies for implementing HVDC in order to connect multiple offshore wind turbines or multiple tidal generators to the grid with an underwater cable.
The statement is: the effects of scaling are good for some creatures and bad for others. I understand the effect of scaling on cubes and the fact that smaller cubes have great surface-area-to-volume ratios.
An airplane flies 200 km due west from city A to city B and then 315 km in the direction of 33.0° north of west from city B to city C.
