A (roughly made) diagram of the circuit is given in the attachment. The red zigzags represent resistors R1 and R2; the blue line is a switch. Why is it that when the switch is closed, no current runs through R2? The explanation I was given was because there is an alternate resistance-free route...but can someone elaborate more on this. Technically, wouldn't the current split along the route?
