"WebJan 26, 2024 · The current can be positive, zero, and even negative. Similarly, current sources supply whatever voltage is necessary to get the desired current. So there is a voltage across the current source. So, we know due to Ohms Law that 3A through a 4 Ohm resistor produces 12V across the resistor. " - Can ohms be negative

Can ohms be negative

WebWhen the circuit analysis is complete, one or more of the element voltages around the loop will be negative with respect to its voltage arrow. The signs of the actual voltages always sort themselves out during calculations. WebThe reason for this is that electrons are negatively charged. They are in a state of high potential when at the negative end and low potential at the positive end. Before physicists knew that electrons moved, they assumed that positive charges were doing the moving.
