So I have a problem that I am working on that requires me to find the voltage drop across a 1000 mA current source, and two 2000Ω resistors that are in parallel. I've added a picture of a circuit diagram for this below.

2. Relevant equations

V = I * R

3. The attempt at a solution

I am not particularly familiar with how constant current power supplies work, but from my understanding, as opposed to a regular battery, current sources push a constant current throughout the entire circuit, and have variable voltage to accommodate different resistances it passes through. So, for the question above, I would think that you could just use ohm's law to solve for the voltage correct? For example, since the resistors are in series, you add them together to find total resistance:

Rtotal = R1 + R2....

Rtotal = 2000Ω + 2000Ω

Rtotal = 4000Ω

We know the current is at 1000mA, so:

V = I * R1

V = I * R2

V = 1A * 2000Ω = 2000V

Am i doing this correctly, or am I not thinking it through right?....

Also, how would I find the Voltage going through the current source itself?

Thank you for any and all answers. New to these boards but have glanced at other problems on here throughout the past couple quarters. This is seriously an invaluable resource.
