time¶

Symbol:: t
Latex:: \(t\)
Dimension:: time

electromotive_force¶

Self-induced electromotive_force as a function of time.

Symbol:: E(t)
Latex:: \(\mathcal{E}{\left(t \right)}\)
Dimension:: voltage

inductance¶

inductance of the circuit.

Symbol:: L
Latex:: \(L\)
Dimension:: inductance

current¶

current in the circuit as a function of time.

Symbol:: I(t)
Latex:: \(I{\left(t \right)}\)
Dimension:: current

law¶

E(t) = -L * Derivative(I(t), t)

Latex:: \[\mathcal{E}{\left(t \right)} = - L \frac{d}{d t} I{\left(t \right)}\]
