Newbs Ohms Law question

you cant make I independently from rest rest will change because they all dependent from each other.

i power supply must be resistance in paralel so it change current and voltage stay same. try add another resistor in paralel you will see difference.

use 10 v 2 resistors by 4 ohm in paralel you will have 5 Amps, increase value of 1 resistor and current will drop, so it will be like variable resistor or adjustment knob in supply and voltage will stay same.

@Yindiddle What you have is a circuit with a voltage source, a resistor and a current source in series. Now what you need to know is that a current source is also a voltage source, but the thing about it is that it adjusts it's output voltage so as to get the set current flowing through the circuit, no matter what other elements are present in it (ideally), i.e., an ideal current source always pushes a set amount of current through the circuit. Ohm's law doesn't break down, oh no. It holds good as always. 1mA*1kohm = 1V, which is the voltage across the resistor. You can see that the nodal voltages on either sides of the resistor is 10V and 9V. And 10-9 = 1V, just like I calculated using ohm's law.

The point is, a ideal current source as we have here in everycircuit comes with an infinite series resistance. Its like an open! So the voltage source can not draw any current while the current source can. BTW, a voltage source can be seen as short.

BTW, take an old ac adapter for a laptop 20V a few amps (three minimum) and connect a DPS3005, volia much more powerful and much smaller and lighter.

Ohms Law, 10V applied to 1kΩ results into 10mA current, right?

@robbi_kiddi says: "According to Ohms law, if we apply 10v To a circuit with 1kohm resistor the I is 1mA"

Putting your words in quotes and pretending they are someone else’s words doesn’t work.

Try electronics rather than lying and harassing other users.

Cool, you have removed one of your latest comments? How was it? "..., are you sure, ..." tell us, what you have manipulated, my little troll @robbi_kiddi ? Since i know you crybullies manipulate threads, i capture all threads you trolls popup, LOL. Have fun with electronics my little liar.

I’m not going to prolong the argument you have started since it is a waste of my time. You will be judged by EC users.

i think we can keep the statemente, you are a bloody liar, have fun with thread manipulation, troll.
