5 QUESTIONS 1. Instantaneous power of an AC signal is not particularly useful in electronics. Why? E amous inventor, Thomas A. Edison, believed that DC current would dominate our future. On ie contrary, Nicola Tesla, another electrical genius, was convinced that the future belonged to AC current. Who was right? 3. The average (mean) value of the sinewaye is zero, When sinewave delivers the power to the load, average power is not zero! Why? 4. Which source would deliver more power to the 10-ohm resistor: a DC source of 10 V or a sinewave having the amplitude (peak) of 10V? 5. Is it possible to obtain the same composite (DC+AC) waveform of Screen 1-1 without using an. external DC source?
