# 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
|
|
- $V = \frac{I (A)}{R (\Omega)}$
|
|
- $V = \sqrt{ P (W) \cdot R (\Omega)}$
|
|
- $V = \frac{P (W)}{I (A)}$ |
