But where was the voltage, the sense of anticipation, the excitement?
The voltage can be regulated from zero to one thousand volts by simply setting a dial.
Ordinarily the voltage begins to rise immediately and uniformly.
If he drew 26 amperes, the voltage would fall, at the house, 26 volts.
The specific gravity is a better guide than the lamps or voltage.
As shown in Fig. 24, the voltage remains almost constant between the points M and N.
The cell becomes different from the rest in gravity, voltage and bubbling.
But the voltage may also be increased, as well as decreased.
The voltage then depends on the speed at which the armature is driven.
A dead cell will not give any voltage on test, may give a reversed voltage reading, or at the most will give a very low voltage.

Electromotive force or potential difference, usually expressed in volts.
electronics
(Or "potential difference", "electro-motive force" (EMF)) A quantity measured as a signed difference between two points in an electrical circuit which, when divided by the resistance in Ohms between those points, gives the current flowing between those points in Amperes, according to Ohm's Law. Voltage is expressed as a signed number of Volts (V). The voltage gradient in Volts per metre is proportional to the force on a charge.
Voltages are often given relative to "earth" or "ground" which is taken to be at zero Volts. A circuit's earth may or may not be electrically connected to the actual earth.
The voltage between two points is also given by the charge present between those points in Coulombs divided by the capacitance in Farads. The capacitance in turn depends on the dielectric constant of the insulators present.
Yet another law gives the voltage across a piece of circuit as its inductance in Henries multiplied by the rate of change of current flow through it in Amperes per second.
A simple analogy likens voltage to the pressure of water in a pipe. Current is likened to the amount of water (charge) flowing per unit time.
