Hi,
My Question:
What is the inductance of a coil if the coil produces an emf of 2.50V when the current in it changes form -28.0 mA to 31.0 mA in 12.0 ms?
For this I know I will need to use this equation:
E=-M(delta I)/(delta t)
My problem is that I was wondering if coming up with a negative inductance is alright.
Thank You
