Homework Statement
There's a DC supplying a current V over resistance R and inductor L in parallel. The circuit looks like this except it's DC http://sub.allaboutcircuits.com/images/02262.png
I need to find the total current.
The Attempt at a Solution
I know that the current through the first resistor is IR = V/R per ohms law, however I'm stuck on the current through the inductor. I first guessed it could be calculated from the impedance IL = V/z = V/iωL, but since ω is the angle frequency and equals zero for DC, I got stuck.
I think I need to apply faraday's law to find the current through the inductor, IL:
V = -ε = d(flux)/dt = L*dIL/dt, and calculate IL from the differential equation.
However, I can't find a physical reason as to why I would want to do that. Is it perhaps because the voltage drives a changing magnetic flux through the inductor?
thanks
