Differentiating Property




Basic Definition

Watts is the SI unit of Power (P).

Volts is the SI unit of potential difference and EMF.



Watts specifies the rate at which energy is transferred.

1 Volt is the defined as the difference in electric potential across a wire when 1A current dissipates 1 Watt of power across the wire.







One formula for watts is:

W = Volts × Current

One formula for volts is:

V = Potential Energy/ Charge
