Witryna8 sty 2024 · So $V,$the voltage across the resistor (defined as the electric potential at the right of the resistor minus the electric potential at the left of the resistor), is negative, while $I,$the current through the resistor, is positive. So it would seem $V = -IR$is the correct relationship, but I don't recall ever seeing Ohm's law written this way. Witryna5 mar 2016 · In general, if you compare the voltage drop across a resistor with the output of a DAC and use this to control a pass element you'll get a programmable current source/sink. Hi, Yes this is what I am doing. But I need to get a negative current output. Hence the drain to 0V and the output of my source to the load.

WitrynaWhether the current is positive or negative depends on if the electrode is regarded as positive or negative electrode. Without such information, it is meaningless to claim the current to be... WitrynaIn metal wires, current is carried by negatively charged electrons, so the positive current arrow points in the opposite direction the electrons move. This has been the sign convention for 270 years, ever since Ben Franklin named electric charges with + and - signs. This convention came about 150 years before the discovery of the electron.
