Watt’s law defines the relationship between power, voltage, and current and states that the power in a circuit is a product of the voltage and the current. Watt ‘s law has many practical applications, and the formula for measuring Watt ‘s Law is P = IV. You may use Watt ‘s law to calculate the voltage, power, ampere, and resistance. Watt’s law can be combined with Ohm’s law to get many useful formulas including P=I2R and P=V2/R. In the study of electronics, many laws and theories exist. These laws enable us to understand the workings of electric circuits and components. One such law is Watt’s law. Watt ‘s law takes its name from James Watt, a Scottish chemist, and engineer. … Continue reading What is Watt’s law?
