Homework Statement
I've recently completed a experiment involving a Driven series RLC circuit. The potential difference across R " a variable resistor >> internal resistance of inductor" was measured.
When calculating the current from the PD across R, should I include the internal resistance of L " the inductor"?
Homework Equations
V=IR
The Attempt at a Solution
If I include L's resistance:
I think this would give a incorrect answers because the PD across R would be less.
So the overall effect would be that the amplitude of current in the components will be reduced, and the measured effect of storing energy in C or L would come out as being very good quality components. Since numerically they would be storing a larger percentage of the supplied energy.
If I don't include L's resistance:
I'm not sure on the affect in the formula when calculating values from this current. Since L is assumed to be a perfect inductor, i.e. all the energy is stored within the magnetic field and not dissipated as heat.
Thanks Danny
