Is there voltage drop across current source

Witryna6 sty 2015 · $\begingroup$ If you have a constant voltage source of say $1V$ across a $1\Omega$ resistor, you get a current of $1A$. The resistor has a voltage drop of … WitrynaThe circuit is open, there is no voltage drop across this resistor, hence A still has a potential of 5V. ... So current through the resistor equals that of the current source, and voltage across the resistor reflects that. For the closed circuit you would have two loops, so current through the resistor must balance the 5V, and the current ...
