$I=\frac{\Delta Q}{\Delta t}$

$I=\frac{\Delta t}{\Delta Q}$

$I=\frac{Nq}{t}$

$I=\Delta Q\times\Delta t$

$I=\frac{\Delta N\times\Delta t}{q}$

 $I_1=I_2-I_3$  

 $I_3=I_1+I_2$  

 $I_1=I_2+I_3$  

 $I_2=I_1+I_3$  

The current flowing through a junction must always add up.

Charge in a circuit is always conserved at a junction.

The current flowing in to a junction equals the current flowing out of a junction.

The sum of the currents at a junction must equal the sum of the raisins.
