How to convert 2 amps to watts

 

How to convert electric current of 2 amps (A) to electric power in watts (W).

You can calculate (but not convert) the watts from amps and volts:

 

2A to watts calculation with voltage of 12V DC

For DC power supply, watts are equal to amps times volts.

watts = amps × volts

watts = 2A × 12V = 24W

 

2A to watts calculation with voltage of 120V AC

For AC power supply, watts are equal to the power factor times amps times volts.

watts = PF × amps × volts

For resistive load without inductors or capacitors, the power factor is equal to 1:

watts = 1 × 2A × 120V = 240W

For inductive load (like induction motor), the power factor can be approximately equal to 0.8:

watts = 0.8 × 2A × 120V = 192W

 

2A to watts calculation with voltage of 230V AC

For AC power supply, watts are equal to the power factor times amps times volts.

watts = PF × amps × volts

For resistive load without inductors or capacitors, the power factor is equal to 1:

watts = 1 × 2A × 230V = 460W

For inductive load (like induction motor), the power factor can be approximately equal to 0.8:

watts = 0.8 × 2A × 230V = 368W
