The Voltage is described as a thrust behind the electricity. Stress can be too referred to as potential difference, electromotive force (EMF) or electrical pressure. Imagine electricity as water flowing through a hose. The pressure (Voltage) is what causes the water (current) to flow out of the hose end. The unit of measurement for voltage is the volt, and the letter for voltage is “V” unless it is used in the formulas to Calculate voltage. In this case, the letter “E” denotes the electromotive force. The voltage is calculated by multiplying current and resistance. This formula is known as Ohm’s law.
