First of all, sorry for this possibly very dumb question, but I just can't convince myself. In the attached circuit diagram, I'm tempted to think that the voltage across R1 is 10V, and this would definitely be true if R1 and V were the only elements in the circuit. But doesn't the presence of R2 and R3 affect the voltage across R1 in some way, since they are both connected to the negative terminal via the same node? R1 = 1 kiloohm, R2 = 2 kiloohms and R3 = 5.1 kiloohms, and the problem asks to find the currents across all three resistors and the voltage across R3. If the voltage across R1 isn't 10V, then I have no idea how to go about solving this problem. Please, any advice would be appreciated.
