Understanding Ohm's Law

Ohm's Law describes the relationship between voltage, current, and resistance in an electrical circuit. 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.

Formula:

\( V = I \times R \)

\( I = \frac{V}{R} \)

\( R = \frac{V}{I} \)

Example:

Let's say we have a circuit with the following values:

• Voltage (V): 12 V
• Current (I): 2 A
• Resistance (R): Unknown

To find the resistance, we can use the formula:

\( R = \frac{V}{I} = \frac{12}{2} = 6 \, \Omega \)

Use the calculator above to experiment with different values of voltage, current, and resistance to see how they are related according to Ohm's Law!
