When one has a 240V line and checks the voltage across the individual lines why does one read 114V and the other 90V?

Where are you checking the wires at? The service panel or at the outlet? If you're checking at the outlet, it looks like some bad wiring somewhere. If you're reading this at the service panel, then the main entrance wires are faulty (or your electric company is faulty). If the outlet is unloaded you have a resistive neutral. Call an electrician now, if you value your electronics.

Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').

Similar to the third wire on an RTD, 2 terminals are the current carrying conductors, 2 for the voltage. There will be a voltage drop across any current carrying connection. The voltage sense lines don't carry any current, so they accruately measure the voltage across the calibrated resistor/shunt.

Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
