1. Find VMAX, VMIN, Vavg, and Vrms of the offset sine wave v (t) = V0 + VA cos (2 πt/T0) V in terms of V0 and VA.
2. Find VMAX, VMIN, Vavg, and Vrms of the full-wave rectified sine wave v (t) = VA sin (2 πt/T0) V in terms of VA. Is the waveform causal or non-causal?
when the load is removed from the generatorthe magnitude of the terminal voltage is 34500V. the generator feeds a delta-connected load through a transmission line with an impedence of 0.8+j6.4. the per-phase impedence of the load is2877-j864.
A tank containing 6000L of water drains out in 30 min. The volume Vof water in the tank after t min of draining isV=6000(1-t/30)2. Find the instantaneous time rate of change of V after 15 min draining.
