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.

When lines of force are cut by a conductor you have magnetic?
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.
Why shunt has four terminals?
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.
Define recovery voltage in circuit breakers?
It is the transient voltage that appears across the contacts of the circuit breaker at or near the zero current instant during arcing period. A high frequency transient voltage appears across the contacts and is caused by the rapid distribution of energy between the magnetic & electric field associated with the station & transmission lines of the system at the zero current. This transient voltage is known as restriking voltage.
Distance between ehv lines?
The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.
Is it An ARC is a high voltage?
The generation of Arc in high voltage lines takes place whenever the voltage is enough to allow current to jump across conductors by breakdown of insulator. Arcing mainly occurs when the insulation properties of insulators are permanently damaged resulting in complete system failure
Why is energy lost in power transmission lines?
Increase the voltage in the lines.
What lines go straight across?
Horizontal lines:)
Do latitude lines go up and down or across?
Latitude lines go -------- (across) And Longitude goes | | | (up & down)
What is the main difference between HT and LT Lines?
It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)
Do individual lines in a parallel circuit have different currents flowing through them?
They can. The current in each "line" (correctly, *branch*) depends on (i) the applied voltage and (ii) the individual resistance in each branch. If the branch resistances are different, the branch currents will be different. Ohm's Law will let you calculate the individual currents.
What does the Ventrical lines on EKG paper represent?
voltage
What is EHV lines?
EHV lines are type of electrical lines commonly used for experimentation in physics. They stand for 'Extra High Voltage' lines.
