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)

How do you find OHM?

Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).


How do you work out the current?

There are three formulas that you can use. Amps = Volts/Ohms Amps = Watts/Volts Amps = sq root of Watts/Ohms


If you have 500 ohms and 2000 watts how do you find amps?

The formula you are looking for is I = sq root of W/R.


What is a difference between vollage and watt?

Watts = Volts / Ohms Watts = Volts x Amps


Formula for watts and 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


Amps to watts?

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.


How do I figure watts if I know voltage and ohms?

Volts time amps equals watts so watts divided by volts equal amps.


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.


What is the power of a parallel circuit with a resistance of 1000 ohms and a current of 0.03 amps?

.9 watts.


What is the wattage of 115 volts and 5 amps?

Ohms law will tell you watts equals volts times amps: 115 x 5 = 575


1200 watts is equal to how many amps?

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).


How are volts ohms and watts affected by each other?

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.
