He simply dug into the ground and found sparks of electricity. He dug more and found huge amounts of electricity and he discribed it as voltage.
Actually Alexzander Volta looked deeper in chemicals and discovered that it created it electricity and called the measurement of it voltage.
In the UK the mains voltage is 240 volts
220 volts, 110 volts, 440 volts, 400 volts, AC or DC voltage. High voltage like - 220 KV, 400 KV, etc
Low voltage by definition means any voltage from 31 to 750 volts inclusive.
The standard voltage conversion ratio from 240 volts to 120 volts is 2:1.
The voltage is ~120 Volts.
This unit is called volts.
The battery voltage on a PT Cruiser is typically 12 volts.
2 volts, 5 volts, 12 volts. New computers need even less voltage.
3.3 volts
...volts.
The output voltage depends on how they're connected; In parallel, the voltage supplied will be 1.5 V. In series, the voltage supplied will be 6 V.
A voltmeter measures voltage in volts.
