Ohms Law Calculator

Ohms Law Calculator is a tool used to calculate the relationship between voltage, current, and resistance in electrical circuits. This calculator applies Ohm’s Law to help users perform circuit analysis quickly and accurately. It is commonly used in electrical engineering and physics classes.

What Does the Ohms Law Calculator Do?

Ohm’s Law clearly defines the relationship between voltage (V), current (I), and resistance (R). Ohms Law Calculator enables you to quickly calculate these three parameters. By knowing the value of voltage, current, or resistance, you can easily calculate the missing parameter. This tool greatly simplifies circuit design and analysis.

Ohms Law Calculator Formula

Ohm’s Law has three basic formulas:

V = I * R

In this formula;

• V: Voltage (Volts),
• I: Current (Amperes),
• R: Resistance (Ohms).

Another formula:

I = V / R

And finally, to calculate resistance:

R = V / I

These formulas are used to calculate various parameters in electrical circuits.

Ohms Law Calculator Example

Example 1: Calculating Current

Let’s assume there is a circuit with 12 volts of voltage and 4 ohms of resistance. To calculate the current, we apply Ohm’s Law.

1. Data:
   • Voltage (V) = 12 V
   • Resistance (R) = 4 Ohms
2. Formula:
   • I = V / R
3. Calculation:
   • I = 12 V / 4 Ohms = 3 Amperes

As a result, the current in the circuit is 3 Amperes.

Example 2: Calculating Voltage

Let’s assume there is a circuit with 2 Amperes of current and 6 ohms of resistance. To calculate the voltage, we will use Ohm’s Law.

1. Data:
   • Current (I) = 2 A
   • Resistance (R) = 6 Ohms
2. Formula:
   • V = I * R
3. Calculation:
   • V = 2 A * 6 Ohms = 12 Volts

As a result, the voltage in the circuit is 12 Volts.

The Ohm’s Law calculator enables you to accurately calculate the relationships between voltage, current, and resistance in electrical circuits. These calculations help analyze your circuits correctly and simplify the solution of electrical problems.
