time¶

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

current¶

Electric current as a function of time.

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

charge¶

Electric charge as a function of time.

Symbol:: q(t)
Latex:: \(q{\left(t \right)}\)
Dimension:: charge

definition¶

I(t) = Derivative(q(t), t)

Latex:: \[I{\left(t \right)} = \frac{d}{d t} q{\left(t \right)}\]
