Voltage, otherwise known as electrical potential difference (denoted ∆V and measured in volts) is the difference in electric potential between two points (adapted from Wikipedia). Voltage can be constant (DC) or varying (AC).

Node analysis with voltage source in matrix form
. \\ V_n\end{bmatrix}$$
In case there is an ideal voltage source connected between a node and the reference, then the voltage of that node is equal to the EMF of that voltage source. … So in matrix form we have(if for example node 1 was connected to an ideal voltage source):
$$\begin{bmatrix}E_1 \\ I_2 \\. \\ . \\ . \\ I_n\end{bmatrix} =
\begin{bmatrix} 1& 0& 0 ... &0 \\
