The voltage required by various solutions may range from 1 to 300 V DC, although most fall in the range of 15 to 21 V. Higher voltages are typically required for thicker coatings formed in sulfuric and organic acid.

The voltage ranged from single digits to 140.

Taking the drill for instance, the voltage can range tenfold from 2.4 to 24 volts.

The voltages used in diagnostic X-ray tubes range from roughly 20 to 150 kV and thus the highest energies of the X-ray photons range from roughly 20 to 150 keV.

The voltage required may range from 4,000 up to 13,200 volts.

This voltage ranges from 0.3 V for germanium diodes up to about 3 volts for certain light emitting diodes.

Early integrated comparators, like the LM111 family, and certain high-speed comparators like the LM119 family, require differential voltage ranges substantially lower than the power supply voltages ( 15 V vs. 36 V).

The differential voltage may range from 0.8 V to 1.4 V, with 1.0 V typical.

The energies available are fairly low, in the range of single joules, the voltages range in tens of kilovolts to over 100 kV, and the powers range in hundreds of kilowatts to megawatts.

The welding current can range from 100 A to 800 A, and the voltage can range between 30 and 50 V. A wire feeder is used to supply the electrode, which is selected based on the material being welded.
