Kirchoff's Law
Kirchoff's voltage law states that the algebraic sum of all branch voltages around any closed path in a circuit is always zero.
What will be the Voltage?
By using Kirchoff's Voltage law, the sum of the potential drops is equal to the sum of the potential rises.
30 V = 2V + 5V + 3V + ?V + 10V + 6V
?V = 4V.
Kirchhoff's Current Law
Kirchhoff's current law states that the sum of the current entering into any node is equal to sum of the currents leaving that node.
What will be the Current I 1, I 2, I 3?
By applying kirchhoff's current law,
I (entering current) = I 1 + I 2 + I 3 (leaving current)
I = V / 1 + V / 2 + V / 3
10A = V [ 1 / 1 + 1 / 2 + 1 / 3 ]
10A = V [ 1 + 0.5 + 0.333 ]
V = 10 A / 1.83
V = 5.46 V
Clearly, by using ohm's law I = V / R
I 1 = 5.46 / 1 = 5.46A
I 2 = 5.46 / 2 = 2.73A
I 3 = 5.46 / 3 = 1.82A
