# Ohm’s Law

## Ohm’s Law

Ohm’s law states that the current is directly proportional to the voltage and vice versa proportional to the resistance. This means that as the voltage increases, the current increases increase at the same rate. When the voltage decreases, the current decreases.

Ohm’s law is also valid for the resistance. CURRENT IS INVERTED PROPORTIONAL RESISTANCE. In other words, if the applied voltage remains the same and the resistance is increased, the current decreases. When the resistance is reduced, the current becomes increase. A higher resistance allowed less current. This means that if the Resistance is increased, the current is reduced. If the resistance is reduced, the Electricity is increased.

This can be represented by a formula as follows:

● V = I x R

● I = V / R

● R = V / I

Where: V = voltage in volts (V) I = current in amperes (A) R = resistance in ohms (Ω)

### What are the 3 formulas in ohm’s law?

Ohm’s Law consists of three fundamental formulas that relate voltage, current, and resistance:

1. V = I * R: This formula relates voltage (V), current (I), and resistance (R). It states that the voltage across a conductor is equal to the current flowing through it multiplied by the resistance of the conductor.

2. I = V / R: This formula relates current (I), voltage (V), and resistance (R). It states that the current flowing through a conductor is equal to the voltage across it divided by the resistance of the conductor.

3. R = V / I: This formula relates resistance (R), voltage (V), and current (I). It states that the resistance of a conductor is equal to the voltage across it divided by the current flowing through it.

These formulas can be rearranged algebraically to solve for any of the three variables (V, I, or R) given the values of the other two variables. They provide a mathematical basis for analyzing and calculating the behavior of electrical circuits according to Ohm’s Law.
