Kirchhoff's Current Law
The algebraic sum of currents entering and leaving any point in a circuit must equal zero.
Stated another way
No matter how many paths into and out of a single point all the current leaving that point must equal the current arriving at that point.
Kirchhoff's Voltage Law
The algebraic sum of the voltages around any closed path is zero.
Stated another way The voltage drops around any closed loop must equal the applied voltages.
