A battery is rated to supply a certain number of volts. However, it actually supplies less, because they are "lost" as the current has to get out of the battery in the first place.(The battery has internal resistance)
The amount of lost volts depends on the current being drawn:
The less resistance a circuit has, the more current is drawn, because it's easier to flow.
Example:
If the circuit has little resistance, it draws a large current and the battery's internal resistance causes more lost volts.
If the circuit has high resistance, it draws a small current and there are fewer lost volts.
This is why when you short-circuit a battery (give it hardly any resistance to go through) it heats up and may explode. A large current is drawn and all the volts are used by the battery's internal resistance.

How do you calculate lost volts?
There's a couple ways. You could count the number of semiconductor junctions, resistances and other voltage attenuators, do all your Ohm's Law and drop calculations to come up with a reasonably good number...but if the circuit has been constructed, you could always just power it up, read the voltages at the supply and at whatever point you're trying to calculate the voltage loss for, and subtract one from the other.
What is the conversion factor from electron volts to volts?
The conversion factor from electron volts to volts is 1 eV 1.602 x 10-19 volts.
How Many volts in a gigavolt?
(1,000,000,000) One billion volts.
What is the difference between electron volts and volts in terms of measuring energy?
Electron volts (eV) and volts (V) are both units of energy measurement, but they are used to measure different types of energy. Volts measure the electrical potential difference between two points, while electron volts measure the energy of particles, such as electrons, in an electric field. In simpler terms, volts measure electrical potential, while electron volts measure the energy of particles in that potential.
How can you calculate current when you have volts power?
Divide Watts by Volts ; this gives you Amps.
What is the difference between the emf of a battery and the lost volts when discharging called?
Internal resistance
How are you losing volts by slicing a wire with 120v the going to 50v?
The voltage is lost at the slice.
How do you calculate lost volts?

What is Voltage drop compensation?
A; The best way to describe is this way the load requires 10 volts but due to wiring and bad connections it gets to be 9v 1 volt is lost on IR drop so to compensate the input voltage needs to be boost up to 11 volts to insure 10 volts across the load
On trace heating 415 Volts if you lose a phase on a 3 phase system what percent of heating have you losed?
1/3 rd lost
Is volts measured by electromotive force?
