Laws

To all, who know how to solve the problems mathematically, something for you all?
Please solve it

Kirchoff’s Current Law (KCL):
At every node, the sum of all currents entering a node must equal zero. Kirchoff’s Voltage Law (KVL):
The voltage law says that the sum of voltages around every closed loop in the circuit must equal zero. Exercise:

Please apply Kirchoff’s Current and Voltage laws to the following figures. Figure 1:
