Kirchhoff's Current Law
Kirchhoff's first law (KCL) says the sum of all currents that enter or leave a junction or node equals 0. Or you could say the current going into is equal to the current going out of a junction or node.
- I_a - I_b =0
- I_a + I_b + I_c - I_d - I_e = 0
Kirchhoff's Voltage Law
Kirchhoff's second law (KVL) says the sum of all voltages in an circuit loop is 0.
- V_a - V_b = 0
- V_a + V_b + V_c - V_d - V_e = 0
