Ohm's Law is really important for understanding how power works in electrical circuits. Here’s a simple breakdown:

1. Ohm’s Law tells us how voltage, current, and resistance relate to each other:

   • Voltage (V) = Current (I) × Resistance (R)
   • In simpler terms, you can write it as: V = I × R

2. Power in Electrical Circuits:

   • Power (P) is about how fast electrical energy is used.
   • You can think of it like this: P = V × I

3. How Power Works:

   • If we use Ohm's Law in the power formula, we get some new relationships:
     • P = I × (I × R) or P = I² × R
     • P = V² / R

By understanding these connections, we can better predict how changes in current, voltage, and resistance will affect power usage. This knowledge is key for designing safe and effective circuits.
