# Volts vs. watts vs, amps?

Wattage = Volts times Amps (W = E x I). - BUT -If the load is reactive (either capacitive or inductive), you must multiply voltage times amperage times power-factor (W = E x I x PF).In an A.C. (Alt... Read More »

Top Q&A For: Volts vs. watts vs, amps

## What is the best combo of volts to amps to kill pernicious weeds like thistles with a cattle prod type device as a 50k taser doesn't work due to ultra low amps?

Volts and amps are linked by a mathematical principle known as Ohm's law. Ohm's law states that V=IR where V is voltage, I is current (amps) and R is resistance. In general, biological systems are ... Read More »

## How many watts in 115 volts?

Watts and Volts are two distinct types of measurement.

## How many watts are in 120 volts?

Power equals volts times amperes. So you have to look at your fuse, e.g. 30 amps and calculate: 120 volts times 30 amps equals 3600 watts.Scroll down to related links and look at "Calculator"

## How to Calculate Wattage From Volts and Amps?

Wattage, voltage and current -- or amps -- are all closely related. Watts are a measurement of power, which is realized by the combination of a device's potential to do work, measured in volts, and... Read More »
