Difference between watt and volt and ampere is as follows:
Watt

Volt

Ampere

Watt is the unit of power.

Volt is the unit of voltage.

Ampere is the unit of current.

Watts= Volts x Amperes

Volts= Watts/Amperes

Amperes= Watts/Volts

Watt can be measured with a wattmeter.

Volt can be measured with a voltmeter.

Ampere can be measured with an ammeter.

The product of voltage and current is called power which is measured in watts.

The potential difference between two points is called voltage which is measured in volts.

The rate of flow of charge is called current which is measured in amperes.
