Definition

A volt is defined as the difference in charge between two different points

Expressed in SI units, a volt is:

V = \frac{kg \cdot m^2 \cdot s^{-3}}{A}

Characteristics

• Voltage is the same in parallel
• The algebraic sum of all voltages in a loop must equal zero. A loop is defined as a closed path through a circuit that encounters no node more than once.

Equations

• V = \frac{I (A)}{R (\Omega)}
• V = \sqrt{ P (W) \cdot R (\Omega)}
• V = \frac{P (W)}{I (A)}
