Voltage Unit Relationships
| Unit | Equal to |
|---|---|
| 1 volt (V) | Base unit |
| 1 millivolt (mV) | 0.001 V |
| 1 microvolt (μV) | 0.000001 V |

Voltage is the electric potential difference between two points. One volt is defined as the potential difference that would carry one ampere of current against one ohm of resistance.
Ohm's Law
V = I × R: Voltage (V) equals Current (I) multiplied by Resistance (R).
I = V / R: Current (I) equals Voltage (V) divided by Resistance (R).
R = V / I: Resistance (R) equals Voltage (V) divided by Current (I).
P = V × I: Power (P) equals Voltage (V) multiplied by Current (I).
