Amps To Resistance

I 100 w 12 v 8 33 amps.

Amps to resistance. How to convert watts and ohms to amps. The resistance r is equal to 12 volts divided by 0 3 amp. The resistance in electrical wires consumes power and the power consumed increases as the current going through the wires increases. Using this analogy let s now look at the tank with the narrow hose.

The current i in amps a is equal to the power p in watts w divided by the voltage v in volts v. It is also possible to convert watts to amps if the resistance of the circuit is known using the formula. How to convert from amps to resistance in 1 step only. What is the resistance of an electrical circuit that has voltage supply of 12 volts and current flow of 0 3 amp.

Ohm volt amp. Resistance r power p each of these quantities are measured using different units. The resistance r in ohms ω is equal to the voltage v in volts v divided by the current i in amps a. Rearrange v ir to solve for resistance.

Using ohms law this gives us a flow current of 1 amp. I a p w r ω. The amount of water in the tank is defined as 1 volt and the narrowness resistance to flow of the hose is defined as 1 ohm. Voltage is measured in volts v current is measured in amps a resistance is measured in ohms ω power is measured in watts w electrical power or the wattage of an electrical system is always equal to the voltage multiplied by the current.

To calculate amps divide the voltage by the resistance in ohms. The current i in amps is equal to the power p in watts divided by the voltage v in volts multiplied by the power factor pf multiplied by 3. Ohms to amps calculation with watts. The current i in amps a is equal to the voltage v in volts v divided by the resistance r in ohms ω.

For example a series circuit is powered by a 12 volt battery and the current is measured at 8 amps. Plug the values you found into this formula to solve for total resistance. ω v a. There is an advantage that comes from using less current to make the same amount of power.

So this latter system produces the same power but with half the current. The simplest way to convert from amps to resistance is by the formula of ohm s law dividing the voltage between the current. Ohm s law provides an alternate formula to find volts if amps and the electrical resistance is known. Enter the power in watts w resistance in ohms ω then press the calculate button to get the result in amps a.

The total resistance across the circuit must be r t 12 volts 8 amps 1 5 ohms. R ω v v i a so. Current a voltage v resistance ω for example let s find the current of a 12 volt circuit with 10 ohms of resistance. The resistance r in ohms ω is equal to the power p in watts w divided by the squared current i in amps a.

R v i resistance voltage current.
