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
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)
Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
You need to know the voltage and Power Factor in the equation Watts = Amps x Volts x Power Factor. Now Power Factor is equal to one for a resistance load and decreases for loads like motors. So for example if you are talking about a home portable electric heater that draws 15 Amps at 120 Volts your Watts would be 15 x 120 = 1800 watts or 1.8 kilowatts.
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
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
The power lost in a resistor is(the current through the resistor) times (the resistance) watts. That's the same thing as(the voltage across the resistor)/(the resistance)watts.
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)
Amps = Watts / (Volts x Power Factor). The Power Factor is one for resistive loads and decreases for inductive loads like motors.
The power used by the coffeemaker can be calculated using the formula P = I^2 * R, where P is power, I is current, and R is resistance. Plugging in the values, we get P = 11^2 * 10 = 1210 watts. So, the coffeemaker uses 1210 watts of power.
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.
The power dissipated across a resistor, or any device for that matter, is watts, or voltage times current. If you don't know one of voltage or current, you can calculate it from Ohm's law: voltage equals resistance times current. So; if you know voltage and current, power is voltage times current; if you know voltage and resistance, watts is voltage squared divided by resistance; and if you know current and resistance, watts is current squared times resistance.
All resistances will emit heat energy when a current flows. The heat production rate (or power) can be found by any of these formulas: Power = Current * Voltage Power = Current2 * Resistance Power = Voltage2 / Resistance. Power is given in Watts when Current is in Amps, Voltage in Volts, and Resistance in Ohms.
Watts is equal to volts x current x Power Factor. The maximum value of Power Factor is 1 for a resistive load. For motors and other inductive devices the Power Factor is less than 1. Your maximum wattage is 10,000 watts and decreases as Power Factor decreases.
There is no direct conversion between ohms and watts as they are different units of measurement. Ohms measure resistance while watts measure power. However, you can calculate power (in watts) using the formula P = V^2 / R, where V is voltage in volts and R is resistance in ohms.
The current [I] (measured in Amps) is equal to the power [P] (measured in Watts) divided by the voltage [V] (in Volts). I = P/V Amps = Watts / Volts Therefore, P*V=I Watts * Volts = Amps
Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
