My friend's breadboard power supply bit the dust the other day, so I wanted to whip up something quick for him. I have a 5V DC wall wart, but I figured I should probably make some sort of short protection. I found this circuit:

My questions are:
1. Will 10 ohms be ok for R1. I don't have a 0.5 ohm resistor.
2. Will C3914 transistors be ok for this application? They look like power transistors but I just want to be sure.
3. Since I'm using a DC supply, shouldn't VP go to Vin (+5V)?
