What is the ratio of watts to volts?

To obtain Volts you need both Watts and Amps: The formula is (W)/(A) =(V). For example, if you have a power of 10W with a current of 2A the voltage is 10W / 2A = 5V. This comes from the equation V = P / I. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.
