(1 pt) A voltage V across a resistance R generates a current I=VR . If a constant voltage of 5 volts is put across a resistance that is increasing at a rate of 0.5 ohms per second when the resistance is 5 ohms, at what rate is the current changing?

Any help? Due in 33 minutes. I know, short notice, but if you can help, please.

ok i got an answer of -.1 ohms/sec. It's saying my units are wrong though. The example in my textbook has ohms/sec though. Is there another name for ohms/sec?

It's asking for the rate of change of current, not the resistance. Current is in amperes or milliamperes, so the units would be A/sec or mA/sec.

Don... 2 minutes after it was due.

Thanks for the help though, it was Amp/s.

I believe the correct answer is: Gah!
