SUMMARY
The configuration of two coils in a circuit significantly impacts voltage readings as measured by a voltmeter. When coil N1, with N1 rings and length L1, is connected to battery V1, and coil N2, with N2 rings and length L2, is connected to the voltmeter, the voltage V2 can be determined using the transformer equation V2 = V1 * (N1/N2). The outcome varies based on whether the coils are ideal or real components, as real coils introduce resistance that affects the final steady-state current and consequently the voltmeter reading.
