Basic Building Blocks of Electronics | Voltage Current, and Resistance |

Updated: May 25, 2023

If you're interested in electronics, it's important to start with the basics. The three basic building blocks of electronics are voltage, current, and resistance. In this article, we'll explain these fundamental concepts in simple terms, so even beginners can understand.

Voltage Current and Resistance

What is Voltage?


Voltage is the measure of the electrical potential difference between two points in a circuit. It's also known as electric tension or electric potential. Voltage is measured in volts (V) and is represented by the letter 'V' in circuit diagrams.

What is Voltage?

What is Current?


Current is the flow of electric charge through a circuit. It's measured in amperes (A) and is represented by the letter 'I' in circuit diagrams. The current flowing through a circuit is influenced by the voltage and the resistance of the circuit.

What is Current?

What is Resistance?


Resistance is the measure of how much a material or device resists the flow of electric current. It's measured in ohms (Ω) and is represented by the letter 'R' in circuit diagrams. Materials with low resistance allow current to flow easily, while materials with high resistance restrict current flow.

What is Resistance?

How are Voltage, Current, and Resistance Related?


The relationship between voltage, current, and resistance can be explained by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance. In other words, if the voltage increases, the current also increases, but if the resistance increases, the current decreases.

How are Voltage, Current, and Resistance Related?

Understanding the basic building blocks of electronics is essential for designing and analyzing circuits. For example, if you want to calculate the current flowing through a circuit, you need to know the voltage and resistance of the circuit.


Conclusion


In conclusion, voltage, current, and resistance are the basic building blocks of electronics. Understanding these concepts is essential for anyone interested in electronics, and it provides a foundation for more advanced topics. By applying these concepts, you can design and analyze circuits with greater ease and accuracy.
