charged electrons (current) are forced through a conducting loop by the pressure of an electrical circuit's power source, they can perform tasks like lighting a lamp. 24 volt is the battery provide.
In a nutshell, voltage equals pressure and is expressed in volts (V). The name honors Alessandro Volta (1745–1827), an Italian physicist who developed the voltaic pile, the precursor of the modern household battery.
Early on, voltage was referred to as electromotive force (emf). This is the reason why the symbol E is used to denote voltage in equations like Ohm's Law.
V= IR
V= ?
I = 2
R = 12 ohms
V= IR
= 12 * 2 = 24 volt
Voltage and the term "potential difference" are often used interchangeably.
Therefore, charged electrons (current) are forced through a conducting loop by the pressure of an electrical circuit's power source, they can perform tasks like lighting a lamp. 24 volt is the battery provide.
