Specifically, it is a flash converter, so named because of its high speed: Explain why we must use a priority encoder to encode the comparator outputs into a four-bit binary code, and not a regular encoder. Because the resistor simply and directly resists the flow of electrons at all periods of time, the waveform for the voltage drop across the resistor is exactly in phase with the waveform for the current through it. in 1831., DC current flows in one direction in a conductor, while AC current flows in both directions. However, for an AC circuit with reactive elements, we have to assess the consumed power differently. First we need to find the total resistance in the circuit. On the other hand, capacitors and inductors have a distinct type of AC resistance known asreactance, as mentioned before(XL and XC). Students learn how to build simple piezoelectric generators to power LEDs.
