For certain motors on alternating current (AC) circuits, a motor controller can also be a general-use snap switch if the switch is suitable only for use on AC (not general-use AC/DC snap switches) and if the motor FLC rating is not more than 80 percent of the switch’s ...

WebMay 22, 2024 · The required load for maximum load power is shown in Figure 5.5.9. Figure 5.5.9: Circuit of Figure 5.5.8 with proper load configuration. We shall repeat the process to find the new load power. i = E Ztotal i = 70V 40Ω i = 1.75∠0 ∘ A Pload = i2 × Rload Pload = (1.75A)2 × 20Ω Pload = 61.25W WebThe output voltage of an AC generator is given by v = (1.20 102 V) sin (30t). The generator is connected across a 0.500-H inductor. Find the (a) frequency of the generator, (b) rms voltage across the inductor, (c) inductive reactance, (d) rms current in the inductor, (e) maximum current in the inductor, and (f) average power delivered to the inductor. WebJun 5, 2024 · Usually, this requires the application of either a Thévenin or Norton equivalent. Finally, although maximum power transfer is a desired outcome in some situations, it is not desirable in all situations. The reason is one of efficiency. At the maximum load power, efficiency is only 50%. fit stop heber release of liability
