How is ohm's releted the power?

Ohm's Law relates voltage (V), current (I), and resistance (R) in an electrical circuit, expressed as V = IR. Power (P) in an electrical circuit can be calculated using the formula P = VI, which can be further expressed in terms of resistance as P = I²R or P = V²/R. This shows that power is directly proportional to the square of the current or voltage, while also being influenced by resistance. Therefore, Ohm's Law provides a foundational understanding of how voltage, current, and resistance interact to determine electrical power.
