Toggle**What Is Ohms Law?**

Before we dive into the details of an Ohm’s Law Calculator, let’s briefly discuss what Ohm’s Law is. Ohm’s Law is a fundamental principle in electrical engineering, named after the German physicist Georg Simon Ohm.

It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. In mathematical terms,

Ohm’s Law is expressed as:

V = I * R

Where:

● V = voltage (in volts)

● I = current (in amperes)

● R = resistance (in ohms)

**How Does Ohms Law Work?**

Ohm’s Law is a fundamental principle explaining the relationship between an electrical circuit’s current, voltage, and resistance. Like water flowing through a pipe, current flows through resistance when a voltage is applied.

To understand this concept better, we can compare it to water flow in a pipe system. In this analogy, voltage represents the water pressure, current represents the flow rate, and resistance represents the pipe size.

When the pipe size is larger and less resistance is present, more water (current) can flow through it when higher pressure (voltage) is applied.

**How to Calculate Ohms Law?**

You can calculate current, voltage, and resistance using the formula V = I x R. In this formula, I represent the current, which is measured in amps and refers to the number of electrons in a circuit.

V stands for voltage, which measures the energy carried by a charged particle. Lastly, R denotes resistance, which is influenced by the conductor type used and measured in amps.

To apply Ohm’s law formula, follow these three simple steps:

**Step 1:** Create a list of the known values for your calculation.

**Step 2: **Write down the unsolved value you need to find in step two.

**Step 3:** Lastly, gather your thoughts and proceed to step three.

**Limitations of Ohm’s Law**

Here are some important limitations to consider when it comes to Ohm’s Law:

**1.** Not all non-metallic conductors follow Ohm’s Law.

**2.** Ohm’s Law does not apply to certain non-linear components, such as:

● Semiconductors

● Capacitors

● Carbon resistors

● Vacuum tubes

● Electrolytes

● Arc lamps using zener diodes

**3.** Ohm’s Law is only applicable to metal conductors operating at a constant temperature. If the temperature changes, the Law does not hold true.

**4.** Unilateral networks, which include components like transistors and diodes, are not covered by Ohm’s Law. Unilateral elements only allow current flow in one direction.

**Conclusion**

The Ohm’s Law Calculator is an invaluable tool for anyone working with electrical circuits. Understanding Ohm’s Law and utilizing the calculator correctly can lead to more accurate results, enhanced circuit performance, and improved safety.

So, the next time you find yourself in need of calculating voltage, current, or resistance, rely on the convenience of the Ohm’s Law Calculator and simplify your electrical calculations.
