Question

Which formula is used with Ohm's Law to help determine power consumption in an electrical circuit?

Options

• \[P = \frac{R}{V}\]

• \[P = VI\]

• \[P = \frac{V}{I}\]

• \[P = \frac{I}{V}\]

Answer 1

Ohm's Law helps determine power consumption using the formula P = VI, where P is power, V is potential difference, and I is current. This is one of the key applications of Ohm's Law in electrical circuits.
