How to Use

Using our Ohm’s Law Calculator is as easy as pie! Here’s how:

1. Visit the calculator interface on our website.
2. Input two of the three parameters: Voltage (V), Current (I), or Resistance (R).
3. Click on the calculate button to reveal the missing variable.
4. Review the results that show how the elements of your electrical circuit interact.

Formula

The fundamental equation of Ohm’s Law can be summarized as follows:

V = I × R

Where:

• V = Voltage (in volts)
• I = Current (in amperes)
• R = Resistance (in ohms)

You can rearrange the formula to find current or resistance:

• I = V / R
• R = V / I

Example Calculation

Let’s assume we have a circuit with:

• Voltage (V) = 12 V
• Resistance (R) = 4 Ω

To calculate the current (I), we use the formula:

I = V / R

So:

I = 12 V / 4 Ω = 3 A

This means a current of 3 amperes flows through the circuit!

Limitations

While Ohm’s Law is incredibly useful, it’s important to be aware of its limitations:

• Ohm’s Law applies only to resistive components; non-linear components like diodes and transistors do not follow this relationship.
• Temperature can affect resistance and, consequently, voltage and current readings.
• In complex circuits, other laws (like Kirchhoff’s laws) may need consideration.
