## Ohm's Law & Power Calculator

### Ohm's Law in Electrical Circuits

Understanding the relationship between current, voltage, and resistance is pivotal for electrical calculations. Ohm's Law provides three core formulas to make these calculations easier:

Voltage (V) = Current (I) × Resistance (R)

Current (I) = Voltage (V) / Resistance (R)

Resistance (R) = Voltage (V) / Current (I)

To apply Ohm's Law in an electrical circuit, follow these steps:
1. Identify Known Variables: Determine which variables you know: Voltage (V), Current (I), or Resistance (R).
2. Choose the Appropriate Formula: Use one of the three formulas based on what you need to find out.
3. Perform the Calculation: Plug the known values into the formula to find the unknown variable.

Note: Ohm's Law is generally applicable for resistive circuits. For circuits with inductors and capacitors, additional laws and formulas may apply.
