Watts are a measure of power, amps are current, voltage is energy. watts=volts*amps. Houses are all 110v AC (at least here in the US). Argument's sake, a 55w lightbulb at 110v is drawing .5 amps (55w=110v*.5a). Power is drawn, not pushed.
Amps are a measure of electric current (a measure of how much electricity is flowing through the wire), Volts are measure of Voltage or 'electric potential difference', and Watts are a measure of power.
If you understand charge, then you understand voltage and current. In a single sentence: Charge is a fundamental dimension, or property, of matter in the same way that matter has mass or volume. Current is a flow rate of charge. Voltage is the quantity of energy available based on how much charge is present.
For the W to V conversion, we can use the formula for electric power: P (W) = I (A) * V (V) To calculate volts from watts, we need to rearrange this formula by expressing voltage like this: Volt = Watts / Amps. To convert watts to volts, we need to know how many amps does the electrical circuit has.
Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current). So, when we talk about these values, we're really describing the movement of charge, and thus, the behavior of electrons.
Convert watts to volts with a simple electrical conversion calculator. See three conversion formulas for an AC or DC circuit.
29 lip 2024 · With Ohm's and Watt's equations you can calculate four variables - power, voltage, resistance and current. If you know the values of two of these variables, you can transform the above equations according to your needs.
