How do you do this?

[Shackleford]

A coil has a 3.25 ohm resistance and 440 mH inductance. If the current is 3.00 A and is increasing at a rate of 3.60 A/s, what is the potential decrease across the coil at this moment?

The only equation I know to use is

emf = - L dI/dt

Hi Shackleford,

What would be the emf across a 3.25 ohm resistor in this situation?

Hello. Sorry. I took another quick stab at this problem and solved it correctly. I've kind of had a cold/mild flu lately.
