ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc).
Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms)
or
Resistance (ohms)=Power(W)/(current x current)
The formula you are looking for is I = sq root of W/R.
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
To convert amps to watts, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. Multiply the current in amps by the voltage in volts to get the power in watts.
To calculate amps, you need to know the voltage of the circuit. The formula to convert watts to amps is Amps = Watts / Volts. If the voltage is 120V, then 1200 watts would be equal to 10 amps (1200 watts / 120 volts = 10 amps).
The formula for watts is, Watts = Amps x Volts.
Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).
There are three formulas that you can use. Amps = Volts/Ohms Amps = Watts/Volts Amps = sq root of Watts/Ohms
The formula you are looking for is I = sq root of W/R.
Watts = Volts / Ohms Watts = Volts x Amps
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
To convert amps to watts, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. Multiply the current in amps by the voltage in volts to get the power in watts.
Volts time amps equals watts so watts divided by volts equal amps.
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.
.9 watts.
Ohms law will tell you watts equals volts times amps: 115 x 5 = 575
To calculate amps, you need to know the voltage of the circuit. The formula to convert watts to amps is Amps = Watts / Volts. If the voltage is 120V, then 1200 watts would be equal to 10 amps (1200 watts / 120 volts = 10 amps).
For a fixed resistance (ohms) current increases as voltage increases. Since Watts equals Volts x Amps x Power Factor then Watts would increase as voltage increases. The resistance would usually be fixed, but if you had a variable load resistance as the resistance decreased and the voltage remained constant, the current would increase and watts would therefore increase. Watts = Volts x Amps x Power Factor Volts = Amps x Ohms Power Factor is 1 for a resistive load.
