Watt vs Volt?

Question

what is the difference between volt and watt?

I see sometimes 100 volt and 23 watt.

Which is more energy consuming?


I know this is laughable but it is serious question

Answer 1

A volt is the measurement of electric potential and the Watt is the measure of electrical energy or in your case a current flow at a rated voltage. You cannot have one without the other. So at a given voltage 100V and a varying current flow you may use 23watts of power. The watt is expressed as energy used (or wasted as in heat). If you look at Ohms law you have Volts = Amps*Resistance and also P(watts) = Volts * Amps. So to find the current flow I=P/V or 23/100=.23Amps. So pretty much they all work together. Hope this helps. Cheers..

Answer 2

A watt is equivalent to a joule/sec. A watt is a unit of power



A Joule is a unit of energy (or work).



A volt is equivalent to a joule/coulomb. A volt is a unit of electric potential difference.



Current is measured in Amps. An amp is equivalent to a coulomb/second.



A coulomb is a unit of charge. The smallest discreet charge possible is the charge on one electron. It takes about 6x10^18 electrons to make up one coulomb of charge.



Power (watts) = potential difference (volts) * Current (amps)



potential difference (volts) = current (amps) * resistance (ohms)

Answer 3

watts (W) and volt-amperes (VA) are units of measurement for electrical power. Watts refer to “real power,” while volt-amperes refer to “apparent power.”

Answer 4

two totally different concpets...

The volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force.

The watt (symbol: W) is the SI derived unit of power, equal to one joule per second.
