How do you solve for current using volts and watts in a problem?
Amperes measure the rate of flow of electricity in a conductor Volts measure electrical pressure Watts measure the amount of energy or work that can be done by Amperes and Volts Relationship: Work = Pressure x Flow or Watts = Volts x Amperes When you know two variables you can calculate the other Formulas - This formula referred to as the West Virginia Formula (W - VA)Watts = Volts x Amps Volts = Watts / Amps Amps - Watts / Volts Refer to link below for more information
How do you convert watts into amperes?
To convert watts into amperes you divide the circuit voltage into the watts. Amps = Watts/Volts. <<>> Converting Watts to Amps The conversion of Watts to Amps is governed by the equation Amps = Watts/Volts For example 12 watts/12 volts = 1 amp Converting Amps to Watts The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts For example 1 amp * 110 volts = 110 watts Converting Watts to Volts The conversion of Watts to Volts is governed by the equation Volts = Watts/Amps For example 100 watts/10 amps = 10 volts Converting Volts to Watts The conversion of Volts to Watts is governed by the equation Watts = Amps x Volts For example 1.5 amps * 12 volts = 18 watts Converting Volts to Amps at fixed wattage The conversion of Volts to Amps is governed by the equations Amps = Watts/Volts For example 120 watts/110 volts = 1.09 amps Converting Amps to Volts at fixed wattage The conversion of Amps to Volts is governed by the equation Volts = Watts/Amps For Example, 48 watts / 12 Amps = 4 Volts Explanation Amps are how many electrons flow past a certain point per second. Volts is a measure of how much force that each electron is under. Think of water in a hose. A gallon a minute (think amps) just dribbles out if it is under low pressure (think low voltage). But if you restrict the end of the hose, letting the pressure build up, the water can have more power (like watts), even though it is still only one gallon a minute. In fact the power can grow enormous as the pressure builds, to the point that a water knife can cut a sheet of glass. In the same manner as the voltage is increased a small amount of current can turn into a lot of watts.
A 14 volt lightbulb is equal to how many watts?
If you have 14 watts, you have 14 watts of power. We measure electromotive force (EMF), which is commonly called voltage, in volts. EMF (voltage) is the force that will drive electron current flow, which is measured in amps. Simply put, power is current times voltage, or, said another way, watts is amps times volts. If you have 14 watts, you could have 14 amps at 1 volt, 7 amps at 2 volts, 2 amps at 7 volts, or any other combination of current and voltage with a product of 14. You may have picked up that because watts is amps times volts, we can say that a watt is a volt-amp. Extending that thinking, 14 watts is 14 volt-amps. There is no way to write 14 watts in volts, at least not without having a bit more information.
Find an expression for power that involves only current and voltage?
That is the basic one. P=I*E. Power in watts (P) equals current flow in amps (I) times the potential voltage (E) in volts.
The primary coil of a step-up transformer draws 110 W. What is the power provided by the secondary coil?
When we look at transformers, we'll generally see that watts in will equal watts out. Said another way, volt-amps in equal volt-amps out. There is a simple relationship between the turns ratio between the primary and secondary and the voltages between those two windings. From there, it's a hop, skip and a jump to figuring out currents. In a one to one transformer, volts in equal volts out. Current in will equal current out, too. Watts in will equal watts out. In a step down transformer with, say, a 10:1 ratio, 120 volts in will produce 12 volts out. And a 1 amp secondary current will appear as a 0.1 amp current in the primary. The 120 volts x 0.1 amps = 12 watts. And the 12 volts x 1 amp = 12 watts. Volt amps in equals volt-amps out, and power in equals power out. Simple and easy. If you are using a step up transformer in, say, a 110 volt to 220 volt application, 110 watts in the primary at the 110 volts will be 1 amp. In the secondary side, 220 volts will appear and 0.5 amps will be the current flow. The 220 volts times the 0.5 amps is 110 watts, as asked about. The secondary has twice the voltage and half the current of the primary side. There are 110 watts in and 110 watts out. Again, simple and easy.
Is 24 watts 24 volts?
"0" zero unless there is current flow. Watts = Amps x Volts.
How do you solve for current using volts and watts in a problem?

How do volts get power?
Volts cause current to flow through the load. The current is measured in amps, and the volts multiplied by the amps gives the power in watts.
4 volts is a many watts?
4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.
How many watts in 6V?
None by itself. Watts are measurement of power, and power is volts times amperes. Secondly, the 6 volts must be in an electrical circuit (loop) to create current flow (Amps). Thirdly, the resistance of whatever the 6 volts is powering determines current flow (Amps). So, without knowing the current flow, you cannot calculate power. Fourth, power (Watts, horsepower, ergs, chevals vapeur, etc) is a measurement taken over a certain time - it is not instantly measureable with an inexpensive meter like a voltmeter or an ammeter (Amp-meter).
How many watts are in 600 volts?
You are confusing electrical potential (Volts) and power (Watts). The equation for power (watts) is P = VI where V is volts (a measure of electrical "pressure") and I is current in amperes (the rate of flow of electricity). If the system is 120V and the power used is 600W then the current used is 5A. If the system is 240V and the power used is 600W then the current used is 2.5A.
What is the procedure to convert kilowattas to kilovolts?
You cannot convert watts to volts. Volt is a measure of potential difference.. in other words the 'push' in the circuit that makes the current flow. Watts are a measure of energy used. V x I = W Where V= Volts I= Current in Amps (A) W= Watts
How do you covert watts to amps?
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
How are amps different from watts and volts?
Amps measure the current flowing in a circuit, watts measure power output, and volts measure voltage difference. In an electrical system, volts x amps = watts, so they are related but measure different aspects of electricity. Volts represent the force pushing electrical current, while amps indicate the rate of flow, and watts show the total power consumed or produced.
What is a tosters power used or current drawn?
Depends on the model, usually there is a information plate on the device showing power consumption in watts, The theoretical current flow can be estimated from : I (current - amps) = Power (watts) / Voltage (volts). > So if you have a 1000 watt toaster @ 230 volts supply, the current in amps = 1000 / 230 = 4.35 amps.
How many watts can can you use with a 20 amp 110 volt outlet?
If you are asking about 220 watts, remember Watts equal power, which is Volts times Amps. Amps are used to measure current - how many electrons flow past a certain point per second - so there is no answer to this question. If you meant to ask what current a load of 220 Watts would take if the applied voltage was 110 Volts, the answer is 220 Watts divided by 110 Volts = 2 Amps.
How much current would flow through a 75 w bulb in a 220 v curcuit?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
