Current flows alternately in both directions, switching directions 50 or 60 times per second. I know. That's why I mentioned + and - signs are at instant time. At certain time, upper is higher voltage than lower. At this time, I'm asking how current direction is determined and why. WebMay 20, 2024 · Thus the current through R1 remains at 0.833 mA. V=IR, R=0, so the current source damages itself trying to provide infinite current. In reality though, current is monitored by potential difference across a resistor, so current will drop very close to zero and still maintain the required potential difference across the sense resistor. raydric ragnarok renewal

WebMar 19, 2024 · 1. You are specifying (pre-determining) the power (VA) to be consumed by the load. So if you do the math the VA value can be satisfied by either 100V x 1000A = 100KVA, or by 1000V x 100A = 100KVA, (same result). So essentially you determined the current flow (at a given voltage) when you specified the VA value. Share.
