Voltage (V) or electric potential difference is what makes electric charges move. We can define voltage as difference in charge between two point.
Watt is a measure of power. One watt (W) is the rate at which work is done when one ampere (A) of current flows through an electrical potential difference of one volt (V) .
Formula to calculate voltage from watts.
Amperes – is the base unit of measurement of electric current.
Example:
Calculate the voltage of a light bulb that uses 100 watts and an amperage of 0.91 amps.
Therefore, the voltage of the bulb is 109.9 volts.
