Okay, so i'm not the best with physics. If someone else wants to take the lead go ahead. 
But I'll get the ball rolling. 
Do you know the Voltage formula?

it's ok @Lionblaze15

barstho · Answer

P = power (watts) 
I = current (amperes) 
V = voltage (volts) 
Now rearrange this formula for V =

It's practically done. Just rearrange the formula for V = and plug and chug and you should get your answers in Volts.
