Hello, readers welcome to the new post. In this post, we will discuss **Introduction to Watts Law. **What’s law explains the relationship between voltage curent and power and defines that power in circuitry is multiple of voltage and current. The normal formula used for measurement of watt’s law is P=VI since it found power so this formula is like the power equation. Through using this law we can find the curent volts, power, and resistance of any circuitry.

Through making combinations with Ohm’s law we can get a different expression that will help us to find different values in circuits. For solutions of different circuits, there are different laws are applied that help us to find different parameters of circuit components. Like these laws watt’s law is used to find power volts and curent. In this post, we will discuss different parameters to find the watt law. So let’s get started with *Introduction to Watts Law*

### Introduction to Watts Law

- Watt’s law makes the relation between power, ampere, and voltage in the circuitry of different components. It states that voltage and current multiple is equal to power.

**The formula of Watts Law**is given here- Power= Voltage x Current or P=V/I
- Voltage =Power/Current or V=P/I
- Current= Power/ Voltage I=P/V

### Watts Law Parameters

- The main parameters of the watts law are voltage, curent, and resistance

**Voltage**

- Voltage is the potential difference between 2 points of circuitry. The difference in potential results in the flow of electrons from high potential to low potential. The unit of volts is the voltage

**Current**

- Current is the flow of charges and their units are ampers. Curent only flow when there is a potential difference exists between two points.

**Resistance**

- The opposition in the flow of current is called resistance and its measuring unit is the ohm

**Power**

- Power is a measurement of the amount of work done in circuitry or power used by components in unit time. In a simple way, power is the amount of energy transferred in unit time. The unit of power is watt or J//s

### Applications of Watts law

- Through the use of power sources, we can find value factual power sources generated by the source. We can use to find the power used by the component in circuits. To find the power curent and voltage source multiply them

- Power needs can be calculated through the use of the watt formula. During the wiring desing creation, it is compulsory to have an estimation of electricity charges. The power need of creation is done by measuring the power rating of each device.
- If we have value of power and volts of the component we can find the current through use of the watt formula I=P/V. The same is also done for voltage when current and power value is given
- The equation found from watt and ohm law can be applied to find the resistance of the component.
