So the resistance R in ohms (Ω) is equal to the square value of voltage V in volts (V) divided by the power P in watts (W): R(Ω) = V 2(V) / P(W)So ohms are equal to the square value of volts divided by watts:ohms = volts2 / watts...
The resistanceRin ohms (Ω) is equal to the powerPin watts (W), divided by the square value of the currentIin amps (A): R(Ω)=P(W)/I(A)2 So ohm = watt / amp2 or Ω = W / A2 Example What is the resistance of an electrical circuit that has power consumption of 30W and ...
Power (watts): Voltage (volts): Current (amps): Resistance (ohms): Watt is a unit of power, within electrical systems wattage corresponds to the amount of power that an electric device uses per second.Volt is a measurement of voltage, volts represent the electrical potential difference or ...
Convert kilowatts to watts: 1 kW=1000 W So, 1 kWh=1000 W×1 h Convert hours to seconds: 1 h=3600 s So, 1 kWh=1000 W×3600 s Convert watts to joules per second: 1 W=1Js So, 1 kWh=1000Js×3600 s Calculate the total joules: 1 kWh=3,600,000 J Therefore, 1 kilowatt-hour ...
Given that Io=10^12 watts/meter^2 , What is the intensity of a sound for which the decibel level of the sound measures 141? round off your answer to three decimal places. Find the current in a circuit if the power is 500 W (watts) and the resistance is 25 ohms. Round off...
P=V2R (where V is voltage in volts and R is resistance in ohms) To convert from watts to milliwatts, multiply by 1000. To convert from milliwatts to watts, divide by 1000. For example, if a device operates at 5 volts and draws 0.1 amperes of current, the power consumption is: P=5V...
heat, or mechanical energy. Electric power is measured in watts.Answer and Explanation: To be able to convert from watts to amps, we have to use the power formula. P=I∗V Now we solve the equation for electric current. {eq}I......
