Converting voltage, measured in volts, to power measured in watts is easy using theWatt’s Lawpower formula. Watt’s Law states thatcurrentis equal topowerdivided byvoltage. Multiplying both sides of this relationship by voltage, we can change this formula to also state that power is equal to...
After making your measurements, you don't have to do the calculations yourself. You can use an online calculator. There is one such calculator in Resources. To get the result in watts, you must express voltage in volts, current in amperes and resistance on ohms. Thus, the watt can be ex...
resistance of the circuit element may be known. By using Ohm's Law ( V = I x R) it is possible to calculate the power if either the voltage or current is known. For example the mains voltage may be known to be 250 volts and the element resistance may be known to be 62.5 Ohms. ...
In some instances, you might know a component’s resistance (measured in ohms) but not the current. In such cases, Ohm’s Law and the power formula can be combined: Watts (W) = Volts (V)2/Resistance (R) For example, a component with a 4 ohms resistance operating at 12 volts would...
The nominal impedanceZ= 4, 8, and 16 ohms (loudspeakers) is often assumed as resistanceR. Ohm's law equation (formula):V=I×Rand the power law equation (formula):P = I×V. P= power,IorJ= Latin: influare, international ampere, or intensity andR= resistance. ...
