Best answer
Ohm's Law relates the voltage, current, and resistance in an electrical circuit. The formula is:

\[ V = I \times R \]

Where:
- \( V \) is the **voltage** (measured in volts, **V**),
- \( I \) is the **current** (measured in amperes or **A**),
- \( R \) is the **resistance** (measured in ohms, **Ω**).

### Units:
- Voltage (**V**) is measured in **volts**.
- Current (**I**) is measured in **amperes (A)**.
- Resistance (**R**) is measured in **ohms (Ω)**.

So, Ohm’s law essentially describes how voltage is related to current and resistance in a circuit, and each of these quantities has its own unit.
