How does the configuration of two coils affect voltage readings in a circuit?

[oronanschel]

Homework Statement

given two coils one with N1 rings legnth L1 the other N2 L2, one inside the other
the radius is not given..
N1 is connected to battery V1 and N2 is connected to volt-meter

what will show the volt-meter? (use N1,L1,N2,L2.V1)

Homework Equations

Faraday's law of induction[

The Attempt at a Solution

Me and my friends tried many ways to solve it but
we couldn't agree

if it is like a normal transformer V2=V1*N1/N2

or is it related to length of the coils

Much will depend upon whether these are real components (coils with some resistance in their windings, battery with some internal resistance, etc.) or ideal components.

If they are "real" components, then coil 1 will reach a final steady state current determined by the battery voltage and the resistance in the circuit. If they're ideal, the current will ramp up indefinitely. These two scenarios will present different results on the voltmeter.
