How many watts in an amp? An amp (ampere) is a unit of electric current, while a watt is a unit of power. The relationship between the two depends on the voltage of the circuit in question. For example, at 120V, 1 amp equals approximately 120 watts. However, at higher voltages such...
A load could be an electronic resistor like this one, or an electrical appliance. © Eugene Brennan How to Work Out Power in a Circuit Knowing the Resistance and Voltage or Current Remember watts = volts x amps? An alternative way to work out power is from the resistance in ohms: So...
A volt-ampere (VA) is a measurement of power in a direct current (DC) electrical circuit. The VA specification is also used in alternating current (AC) circuits, but in this case, it representsapparent power(represented in VA), which often differs from true power (represented in watts). ...
kVA (kiloVolt-Ampere) is a compounded unit. It’s comprised of both electrical potential (Volts) and electrical current (Amps). 1 kVA is a frequently used unit; it represents 1,000 Volt-Amperes. In many cases, it’s useful toconvert kVA to amps. The most common question here is‘How ...

Ampere, commonly shortened to Amp and represented by “A”, is theSI unitused for current. An amp describes the speed of current flow through a circuit. Current is the flow of charge in a conducting material. One amp is equivalent to the movement of 6.24 × 1018electrons through a point...
A choke is simply one long wire wound in many loops. A choke will have two leads which are simply the two ends of the one long wire. The wire is usually looped around an iron core which makes it work better. Looping the wire increases the effect of the induced magnetic field ("induct...
Check your computer’s specifications to see how many watts the power supply unit (PSU) can provide. If you can’t find any specifications, you should be able to see the output on your computer’s power supply. You’ll need to look inside the case, for something like this: ...
How to convert Watts to units of electricity? What are the standard units of electrical energy? Is kilowatt a unit of energy? How many joules are in a watt? What electrical unit is equivalent to one Joule? Is watt a unit of energy?
LED current = 350mA, let's take it 300mA or 0.3Amp to keep things cooler. Substituting these in the formula: R = (U - LEDfwdV)/LED Current = 12 - 9.9/0.3 = 7 ohm watts may be calculated as Watts = LEDfwdV x LED current = 9.9 x 0.3 = 2.97 watts or 3 watts...
