How convert Watts to Amps and vice versa?
Use the following formulas to calculate:
1) Power = Electric potential * Electric current
2) Electric current = Power / Electric potential
3) Electric potential = Power / Electric current
Legend:
W - Watt (power)
A - Amperes (electric current)
V - Volt (electric potential or voltage)
The watt (W) is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer.
The ampere (A or amp) is the base unit of electric current in the International System of Units (SI).
The volt (V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
