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 are the losses in resistors?

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.


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)


How do you calculate the amperage given the watts and voltage?

Amps = Watts / (Volts x Power Factor). The Power Factor is one for resistive loads and decreases for inductive loads like motors.


When a coffeemaker has a resistance of 10 ohms and draws a current of 11A what power does it use?

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.


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.


How do you calculate power loss from a resistor?

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.


What is resistance power?

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.


How many watts is 10kva?

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.


What is equivalent of 1omh to watt?

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.


What is the formulae for the relationship between amps volts and resistance?

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


How do you solve watts to amperes?

Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
