State ohm's law and write the formula down, showing the relation between V (voltage), I (current) and R (resistance).

1 answer

Ohm's Law states that the current \( I \) flowing through a conductor between two points is directly proportional to the voltage \( V \) across the two points and inversely proportional to the resistance \( R \) of the conductor.

The formula representing Ohm's Law is:

\[ V = I \cdot R \]

Where:

  • \( V \) is the voltage (in volts, V),
  • \( I \) is the current (in amperes, A), and
  • \( R \) is the resistance (in ohms, Ω).

This relationship allows you to calculate any one of the three quantities if the other two are known.
