Thanks for the reply! In my work, I actually meant kg :) I did figure it out though, all thanks to you saying "energy stored in the inductor." I realized that I could use the equation U = 1/2 L (i^2), where U is the energy, and simply solve for i. For some reason, the stored energy part didn't...
Homework Statement
How much current is needed in a 9.00mH inductor so that the stored energy will be enough to heat 285g of water from 20.0 degrees Celsius to the boiling point of 100 degrees Celsius? Specific heat of water is 4190 J/kg*Celsius.

Ah, ok. I figured it out. My final answer ended up being 1/Leq = (L1+L2) / L1L2, which will simplify to 1/Leq = 1/L1 + 1/L2. Thanks! I guess I just needed someone to confirm I was on the right track.
Homework Statement
In lab, we were instructed to create a circuit that uses nichrome wires and identical bulbs to measure the obstacle caused by an object. To do this, we slid the alligator clip along the nichrome wire until the 2 bulbs in parallel are the same brightness. The object that we...
