## Introduction To Electricity

Electricity is one of the most important topics in class 10th. It can be used to understand the working of appliances and machines around us. It also helps us to calculate the electrical power of appliances and machines. To understand electricity and its related concepts, it is important to learn all the formulas related to it. In this article, we will discuss all the formulas related to class 10th electricity.

## What Are The Different Formulas Of Class 10th Electricity?

The different formulas of class 10th electricity are as follows:

- Ohm’s law
- Kirchhoff’s law
- Power Formula
- Voltage Formula
- Current Formula
- Resistance Formula

## Ohm’s Law

Ohm’s law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points. This can be mathematically represented as V = IR, where R is the resistance of the conductor. This equation is used to calculate the current, voltage and resistance in a circuit.

## Kirchhoff’s Law

Kirchhoff’s law states that the sum of the currents entering a node is equal to the sum of the currents leaving the node. This law is used to calculate the current in a circuit. It is also used to determine the equivalent resistance of a circuit.

## Power Formula

The power formula states that the power (P) consumed by a circuit is equal to the voltage (V) multiplied by the current (I) flowing through it. This equation is represented as P = VI and is used to calculate the power consumed in a circuit.

## Voltage Formula

The voltage formula states that the voltage (V) across a circuit is equal to the product of the current (I) and the resistance (R). This equation is represented as V = IR and is used to calculate the voltage in a circuit.

## Current Formula

The current formula states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R). This equation is represented as I = V/R and is used to calculate the current in a circuit.

## Resistance Formula

The resistance formula states that the resistance (R) of a circuit is equal to the voltage (V) divided by the current (I). This equation is represented as R = V/I and is used to calculate the resistance in a circuit.
