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


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


What is the formula to find watts?

There are several ways to find watts; volts x amps = watts or resistance (ohms) divided by amps squared or volts squared divided by amps. You can search for Ohm's Law to find examples of these different methods and sample calculations.


What are watts amps and ohms?

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)


What is a difference between vollage and watt?

Watts = Volts / Ohms Watts = Volts x Amps


Amps to watts?

Watts = Amps x Volts Amps = Watts / Volts you only need to know two of the three to work out the other so 230 volts at 10 amps gives 2300 Watts (2.3 kW) 2.3kW at 230 volts draws 10 Amps


How many watts in 0.8 amps?

There are zero watts related to 1.8 amps. Watts are the product of amps times volts. The equation that is used to find watts is Watts = Amps x Volts. Insert the circuit voltage into the equation and you will find the circuit's wattage load.


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

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


Can i use 10amp fuse for 1000 watts instant heater?

There are zero amps in 1000 watts. Watts are the product of amps x volts or I = W/E, watts divided by voltage. As you can see, that if no voltage is stated no amperage can be given. Once you find the voltage of the heater then use the following equation, Amps = Watts/Volts to find the current draw of the 1000 watt heater.


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.
