I'm trying to understand the answer to 2 questions involving this circuit (attached)
Q. 1 and the answer say: if R3 opens the voltage across it will decrease.
Q. 2 and the answer say: if R1 opens the voltage across it will stay the same.
Why doesn't the voltage decrease for both of them? My understanding is that this is a simple parallel circuit with 3 branches, so shouldn't an open in one resister be the same as any other?
