![]() Using Ohm's law above, we can rewrite the power P asġ - Ohm's law and Power Calculator Given Voltage and Resistance Enter the resistance in Ohms and the voltage in volts as positive real numbers and press "Calculate Current and Power".Ģ - Ohm's law and Power Calculator Given Power and Resistance Enter the power in Watts and the resistance in Ohms and press "Calculate Voltage and Current". Equations The equation can be rearranged using algebra. The rate at which heat is dissipated in a resistor is called power P and is given in terms of current I and voltage V by: Calculate Current from Power & Voltage (I P / V) Inputs Power Voltage Output Current Calculate Power Dissipated in a Resistor (P I2 R) Inputs Current Resistance Output Power P V XI. Ohm's law expresses the relationship between the current I passing through a resistor and the voltage V across that resistor of resistsnce R as follows: Just enter 2 known values and the calculator will solve for the others. This W for the unit watt must not be confused with the previous W for the dimension work. So power is, what is done by enduring work. In physics, power is work per time, PW/t. 52 Electron contamination, 112 Electron Delay Storage Automatic Calculator (EDSAC), 183 Electronelectron interactions, 31 Electron energy levels. A branch of physics, a science that studies the motion of material bodies and the. Calculate Power, Current, Voltage or Resistance. Calculate the power from work and time, with different units. This calculator also calculates the voltage and current through a resistor given the power dissipated by this resistor. And since the expression for work is forcedisplacement, the expression for power can be rewritten as (forcedisplacement)/. D - the optical power of the lens(dioptre). This vehicle online calculator is designated for rough calculation of a vehicles power consumption driving at constant speed. See Also: Work, Energy and Power - How to Understand and Calculate an. Wrong: 3,141.An online calculator to calculate the current passing through a resistor using Ohm's law and the power dissipated in a resistor given the voltage across the resistor. In physics we say that work is done on an object when you transfer energy to that. ![]() Very important: Please use the dot as decimal separator: Correct: 3.141. SI unit for work is newton-meters (N.m) or. The SI unit to calculate the power is watt (W, which is equal to one joule. Electrical power is the product of voltage and. Air temperature of 25 Degree Celsius and driving at sea level have been taken into account within standard conditions of air-drag and driving resistance. Work calculator in physics to find the work done on an object which moves through a distance by a constant force. In Physics, power is defined as the amount of energy transferred per unit time. Current is the rate of electric charges moving through a conductor. ![]() exp, e (the Euler Constant) raised to the power of a value or expression. This vehicle online calculator is designated for rough calculation of a vehicle's power consumption driving at constant speed. You will see what the calculator thinks you entered (which may be a little.
