Ohms Calculator

How to Use the Ohm’s Law Calculator

The Ohm’s Law Calculator is designed to help you calculate the electrical parameters of voltage, current, resistance, and power using Ohm’s Law. Follow these steps to input your data and obtain results:

Step 1: Enter Voltage

• Locate the field labeled Voltage (V).
• Enter the value for voltage in the input box. Make sure to enter the value in volts.
• This field is required, with a minimum value of 0, and you can enter values with a precision of up to 0.01 volts.

Step 2: Enter Current

• Find the field labeled Current (I).
• Input the current value in amperes in the designated field.
• This field is mandatory, should be a minimum of 0, and is accurate to 0.001 amperes.

Step 3: Enter Resistance

• Look for the field marked Resistance (Ω).
• Provide the resistance value in ohms in the respective placeholder.
• This field is also required, holds a minimum of 0, and supports input resolutions of 0.01 ohms.

Step 4: View Calculated Results

After entering the values, the calculator will compute several results automatically. These results will be displayed in the fields below:

• Calculated Voltage (V = I × R): This displays the voltage calculation based on the current and resistance you entered and is formatted to two decimal places with a suffix of ” V”.
• Calculated Current (I = V ÷ R): This shows the current calculated from the given voltage and resistance, formatted to three decimal places with a suffix of ” A”.
• Calculated Resistance (R = V ÷ I): Provides the resistance computation based on voltage and current, rounded to two decimal places and ending with ” Ω”.
• Power (P = V × I): Indicates the power determined by multiplying voltage and current, with the result displayed to two decimal places and followed by ” W”.

By following these steps, you should be able to effectively use the Ohm’s Law Calculator to analyze and understand your electrical circuits.
